Remote desktop latency

But back then I did not have to complete with Netflix and Hulu, YouTube and online gaming, or a half dozen smartphones streaming Spotify in my house. Gradually over the past few years, it seems my entire house connected to the Internet. These connected devices have brought many conveniences and more than a little entertainment, but they also brought aggravation when working from home in the form of laggy remote desktop connections, spotty VoIP, and staggering video conferences.

A few years ago my work from home experiences really started to suffer. My first reaction was to call my ISP and have them check speeds and equipment. It is always the other guys' fault when it comes to spending time troubleshooting! Of course, the answers I got back were that everything was running as it should.

So my follow-up questions were, "Can I go faster and how much is it? Here is why more speed may not help. The issue, in many cases, is not your "Internet speed" or bandwidth. The longer it takes to get a response, the higher your latency, and the slower everything feels.

Latency is separate from bandwidth speed. You can have really high bandwidth but also really high latency and that will create a "slow" Internet connection.

Performance Tuning Remote Desktop Session Hosts

The Internet provider sells bandwidth and on their network they try to keep latency low. If an ISP has high latency, they will fix it because it affects their service and all their customers.

So if you experience high latency, it is most likely coming from inside your house. Most people use the ping command to test latency. It is measured in milliseconds ms. It is important to remember that you are running this test at a specific point in time. So a good latency now does not mean it is not bad at other times.

Latency fluctuates based upon the amount and TYPE of Internet traffic going on in your whole house at the moment you check it. So if you have speed issues it is best to test your latency while you are having the problem.

On the support desk when we test for latency, users like to say "My Netflix works fine". Well, that load screen when starting a movie was the video buffering which covers up your latency issue.

On the other hand, activities like Voice over IP calls, Skype calls and video, and remote desktops are greatly impacted by higher latency. How to Address High Latency.

Addressing every possible cause and solution to latency issues is the subject for a book. But knowing there may be a latency problem and what the likely culprits are may be helpful in your own troubleshooting.

Some of the things noted above are just a part of working remotely. As long as you know what is causing the latency then you can plan for it and not worry about it.

As you may have surmised, the biggest culprits who produce latency are your family. While you toil away on your laptop breaking rocks, they game.

They watch videos. They download music. They create latency. Years ago, while I was waiting for that Internet upgrade, I noticed a pattern. Working from home from 8am to 3pm everything went fine. I scheduled my Windows Updates and anti-virus updates for after 7pm when I was supposed to be finished working.

When I moved large files up or down I knew that my remote desktop might hesitate for a moment here and there.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. I've seen: Terminal server performance over high latency links.

It's all currently virtualized on a vSphere 5. Due to facility problems and an increase in offsite and remote users, there is a push to move the systems to a datacenter facility. The new site will feature higher-end vSphere hosts and all-flash storage. Connectivity to the co-location facility will be established via site-to-site VPN with multiple ISPs and failover in place. Is this a bad idea, though? As long as their response times are under ms we don't get complaints but ymmv.

It was a heck of alot easier to replicate the network conditions locally then moving my applications twice.

I feel like this is sort of subjective, as some users won't be happy unless the latency is just like a local desktop experience, and other users will be happy and not complain even if latency is ms. It's true that latency is a user experience-killer, though, precisely how much is a matter of individual perception.

This is a pretty good video from TechEd on user experience in scenarios similar to this this video is about VDI, but it's a similar experience to Remote Desktop Services. This question cannot be answered truly universally and objectively. The results really depend on the workload type and users' demands.

Nothing can be better here than UX tests. I often work remotely over RDP from different locations, most of the time connecting via LTE 4G network which offers latencies similar to 62 ms. Even with the latter value I have a hard time with web browsing or viewing large graphics especially without AdBlock, the graphics-rich sites can render for a few seconds in Firefox!

Also an attempt to write a simple document using Microsoft Word generated some frustration due to a below average interface responsibility in turn LibreOffice Writer felt much better. Not to even mention any work with videos The things I can pretty comfortably work with are MMC, Outlook mail to some degreefile browsing and generally system administration tasks.

This value should be OK for remote system administration and similar tasks you do routinely and have an experience with. But if it's to replace the local screen completely I'd expect frustration and complains. One thing to add - I work under Ubuntu with rdesktop 1. There may be some optimizations in Microsoft's original client or others which can improve the performance with high latency links.

Subms latency is likely not going to be a problem unless your customers are gaming over this network. But you might run out of bandwidth in certain, graphics-intensive applications especially video playbacks which will affect the latency adversely and push it well beyond ms, annoying your users.

RDP 8 Server and later does come with optimizations read: lossy compression algorithms for these scenarios.Selecting the proper hardware for performance. Tuning applications for Remote Desktop Session Host. Remote Desktop Session Host tuning parameters.

For an RD Session Host server deployment, the choice of hardware is governed by the application set and how users use them. The key factors that affect the number of users and their experience are CPU, memory, disk, and graphics. This section contains additional guidelines that are specific to RD Session Host servers and is mostly related to the multi-user environment of RD Session Host servers.

CPU configuration is conceptually determined by multiplying the required CPU to support a session by the number of sessions that the system is expected to support, while maintaining a buffer zone to handle temporary spikes. Multiple logical processors can help reduce abnormal CPU congestion situations, which are usually caused by a few overactive threads that are contained by a similar number of logical processors.

Therefore, the more logical processors on a system, the lower the cushion margin that must be built in to the CPU usage estimate, which results in a larger percentage of active load per CPU. OSMem is how much memory the operating system requires to run such as system binary images, data structures, and so onSessionMem is how much memory processes running in one session require, and NS is the target number of active sessions. The amount of required memory for a session is mostly determined by the private memory reference set for applications and system processes that are running inside the session.

Shared code or data pages have little effect because only one copy is present on the system. One interesting observation assuming the disk system that is backing up the page file does not change is that the larger the number of concurrent active sessions the system plans to support, the bigger the per-session memory allocation must be. If the amount of memory that is allocated per session is not increased, the number of page faults that active sessions generate increases with the number of sessions.

By increasing the amount of memory that is allocated per session, the probability of incurring page faults decreases, which helps reduce the overall rate of page faults. Storage is one of the most overlooked aspects when you configure RD Session Host servers, and it can be the most common limitation in systems that are deployed in the field. The disk activity that is generated on a typical RD Session Host server affects the following areas:. Ideally, these areas should be backed up by distinct storage devices.

Using striped RAID configurations or other types of high-performance storage further improves performance. We highly recommend that you use storage adapters with battery-backed write caching. Controllers with disk write caching offer improved support for synchronous write operations. Because all users have a separate hive, synchronous write operations are significantly more common on an RD Session Host server.

Registry hives are periodically saved to disk by using synchronous write operations. To enable these optimizations, from the Disk Management console, open the Properties dialog box for the destination disk and, on the Policies tab, select the Enable write caching on the disk and Turn off Windows write-cache buffer flushing on the device check boxes. For example, applications handling text processing and data input consume bandwidth of approximately 10 to kilobits per second, whereas rich graphics and video playback cause significant increases in bandwidth usage.

Back-end connections such as roaming profiles, application access to file shares, database servers, e-mail servers, and HTTP servers. Desktop apps are usually optimized toward responsiveness with the goal of minimizing how long it takes an application to respond to a user request.

However in a server environment, it is equally important to minimize the total amount of CPU usage that is needed to complete an action to avoid adversely affecting other sessions. Consider the following suggestions when you configure apps that are to be used on an RD Session Host server:.

Typical examples are disabling background grammar and spell check, data indexing for search, and background saves. Disabling such behaviors or increasing the interval between polling iterations and timer firing significantly benefits CPU usage because the effect of such activities is quickly amplified for many active sessions. Typical examples are connection status icons and status bar information updates.I have a windows 10 pro laptop with remote desktop setup allow remote connections to this computer.

I remote into the laptop from a PC. I just noticed that when the laptop display is turned off set to turn off after 10minsthere is delay in keystrokes and mouse movements when the laptop is accessed remotely. When I wake up the laptop screen by pressing a key on the keyboard or moving the mouse, the delay is gone when accessing the laptop remotely until the laptop screen goes off again in 10mins.

How do we fix this issue? The current workaround is to set the 'turn off the display' to 'never'. Please remember to mark the replies as answers if they help. If you have feedback for TechNet Subscriber Support, contact tnmff microsoft. The lagging is gone once I wake up the laptop screen by pressing a key on the keyboard or touching the touch pad but it will come back once it goes to sleep again. Sorry, I cannot reproduce your issue on my environment. It is best to test from a clean install so you know there can't be anything else that could be causing this problem:.

Have you encounter this issue on the same laptop when you install another version of Windows ever? As soon as the screen of the Surface Pro 4 turns off the keyboard and mouse input in the remote desktop session on the Surface Pro 4 are lagging behind.

If you make the screen of the Surface Pro 4 turn on again press a key on the surface type cover for examplethe remote desktop session running on it responds to user input fast again. Workaround is to keep the screen of the Surface Pro 4 turned on. Either by disabling screen sleep, or setting it to a value of 1 hour and touch a key on the Surface Type cover once an hour.

The following thread describes the same problem as this thread. And it can also be fixed by preventing screen sleep on the Surface Pro. I found the cause of this problem. Via remote desktop I can do whatever typing, working, compiling - the surface pro 4 never gets out of "Connected Standby" and the UI is lagging. As soon as I make the screen wake up by pressing any key on the type cover connected to the surface pro 4, so that the login screen appears, the system gets out of "Connected Standby".

I had hoped that the "Creators Update" would have fixed this, but nope, same problem. Same solution - disable "Connected Standby". You have to use "Hibernate" instead of "Sleep" then and waking up from "Hibernate" can take a few seconds but for me that is ok. Same problem here, since version I experience slow response on keyboard and mouse by RD connection.

I have a Surface Pro 1 tablet. I have similar issues on my surface pro 3 connected with surface dock, and remote access by RDP outside from another windows 10, when screen off, the response from keyboard mouse response will significantly slow and lag. I tried two different source machines I'm connecting from, one is Windows 8. The behavior occurs on both. It doesn't matter what options I select in the Remote Desktop "Experience" connectivity section.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Super User is a question and answer site for computer enthusiasts and power users. It only takes a minute to sign up. If I was doing more thinking-oriented tasks the delay would be okay, but I am honestly losing so much productivity it's driving me insane. I've googled and asked IT here, but I can't figure out if there's a bottleneck somewhere that can be widened, or if this is just the nature of working from home. Do WFH'ers really just have to put up with delay?

When you use a Remote Desktop Connection, it optimizes the experience by disabling anything related to graphics. Switching between applications or scrolling on a website means that there's lots of new pixels that has to be sent over the RDP connection, thus the amount of data to send is substantially larger than just browsing.

In order to fix this, the connection at the office has to have a higher upload speed, but even then it will still hurt performance. Is it possible to VPN into your office? If so, I would RDP to code, and use your local webbrowser to test the webpages. Given that it is the switching and scrolling on webpages that hurts performance most, this is where you can gain most speed. You can use mstsc -v:server -h height -w width to create a custom sized rdp session so you can have an RDP session open on the left side of your screen and a webbrowser on the right side if your screen resolution is big enough to work like this or use a 2nd monitor.

My mouse moves around perfectly but during random periods of time, any time I "click", the click is queued instead of executed right away. It takes several seconds to catch up. This has to be a bug. JoePhillips If you have a modern server environment, then it is quite likely you are experiencing windows stopping and starting the Remote Audio driver.

You are basically waiting for sound to be played, which causes lag. To test this, start a media player on the RDP environment that plays anything, doesn't matter. You can even set the volume to 0. Just make sure it keeps the audio driver busy, and you'll notice the lag is gone.

JoePhillips I am experiencing the same thing. Every so often a mouse click or key press will take a few seconds to register. Did you resolve the problem somehow?Hello, There are many factors to consider why a connection to a server may perform poorly as expected when using Remote access to your Windows 10 PC. First, you need to check for programs installed to your system that may conflict or interfere with the remote connection. Settings that need to be checked with your local host PC is the installed anti-virus software and firewall settings that may affect the connection.

Next is the current configuration and setup of your home network. Another possibility is the service level performance of your Internet service provider. You may need to contact them for proper configuration of your network and consult with them if there are any performance issues to a specific connection or server that may affect your region. Since you are using a VPN service, this may also affect the performance of your remote access to your PC.

Different VPN providers have different ways of connecting through networks and compatibility with your device, network, and Internet service provider are things that need to be investigated.

Having said these points, there are other possible things that you can check and settings that may try to improve the latency of your remote access sessions. I recommend that you post your query on the TechNet Microsoft Forumswhich is more geared towards IT Pro audience and Enterprise environment discussions. Did this solve your problem? Yes No. Sorry this didn't help. Site Feedback. Tell us about your experience with our site.

Hello, I currently have a Windows 10 home server that I manually added Remote desktop conection since it does not have the remote access function preinstalled. Why is the latency huge when I have no problem with remote access tools like Anydesk interactions are instantaneous since the latency is low? Can you please help me and possibly find a solution?

Ferdz Amp Microsoft Agent.When using a remote Windows session, your network's available bandwidth greatly impacts the quality of your experience. Different applications and display resolutions require different network configurations, so it's important to make sure your network is configured to meet your needs.

The following recommendations apply to networks with less than 0. These recommendations apply regardless of how many sessions you're hosting on your virtual machines VMs. The following table lists the minimum recommended bandwidths for a smooth user experience.

These recommendations are based on the guidelines in Remote Desktop workloads. Keep in mind that the stress put on your network depends on both your app workload's output frame rate and your display resolution. If either the frame rate or display resolution increases, the bandwidth requirement will also rise. For example, a light workload with a high-resolution display requires more available bandwidth than a light workload with regular or low resolution.

Other scenarios can have their bandwidth requirements change depending on how you use them, such as:. Make sure to load test these scenarios in your deployment using simulation tools like Login VSI. Vary the load size, run stress tests, and test common user scenarios in remote sessions to better understand your network's requirements. Different display resolutions require different available bandwidths. The following table lists the bandwidths we recommend for a smooth user experience at typical display resolutions with a frame rate of 30 frames per second fps.

These recommendations apply to single and multiple user scenarios. Keep in mind that scenarios involving a frame rate under 30 fps, such as reading static text, require less available bandwidth.
