May be the end of using WSL2 for me as a result. I used to use the same containers on Docker for Windows and they worked fine so I don't think it's something with my docker-compose.yml file. To fix this Hyper-V/Host VBS compatibility issue, VMware’s platform team re-architected VMware’s Hypervisor to use Microsoft’s WHP APIs. Hyper-V is disabled. Hyper is solid in the sense that it never crashed or had a show stopping bug. Now I'm not getting back to Hyper-v... An error has occurred .. How can I go back, would you know? I recently joined the Windows Insider Program,on the slow ring, to be able to test a development version of thesoon-to-be-released Windows Subsystem for Linux, version 2, henceforth WSL2. dism.exe /Online /Disable-Feature:Microsoft-Hyper-V. Windows Subsystem for Linux (WSL) 2 introduces a significant architectural change as it is a full Linux kernel built by Microsoft, allowing Linux containers to run natively without emulation. The download's the same though, I've been getting around this issue by disabling "Large Send Offload". Ubuntu-20.04 If you still want to use Linux inside of WSL along with virtual machines in Virtualbox, consider downgrading some or all your Linux distros from WSL2 to WSL. I suppose it's possible that the Ethernet driver is somehow interacting with WSL and/or HyperV better. Speedteswt from WSL are poor compared to CMD. Monitor failed and slow network requests in production Deploying a Node-based web app or website is the easy part. In fact, they are nearly identical to those of much earlier Windows versions such as Windows 7 and Windows 8. Speeds on WSL seem to be about 10-20 kb/s wheras windows download speed seem to be correlating to my ISP spec of 100/10 Mbps or above. I opened 20 WSL terminal windows and when idling, it barely used any CPU at all. With this tool you don't need to make a dual boot setup in your PC to have all the potencial of Linux because WSL gives you all what you need to start the developent ASAP, but of course WSL have some flaws like slow performance for I/O, slow file system mainly. Performance with Linux or WSL is fine. How do you execute your docker command then from your WSL or from your windows ? I'm seeing same issue. to your account, Windows build number: 10.0.19041.84 The performance gain was also huge and I didn't notice any latency. Your email address will not be published. Speed when transferring between file systems is a little slow right now. Did they improve Hyper-V or did they stop using a virtual machine and create some magic to run the Linux kernel in parallel? The minimum hardware requirements for running Windows 10 are very modest. Is there a solution? Speedtest is showing wrong numbers. To confirm Pengwin was converted to WSL2, run the following command again: wsl -l -v. Welcome to WSL2. However, since WSL 2 now runs on a Linux kernel with full system call capacity, Docker can fully run in WSL 2. I'm hitting this issue, as well. The performance difference was huge, basic php pages that were taking about 8 seconds on WSL2 were now loading immediately with Hyper-V. Please see the video of my testing. @Biswa96 For people who need windows for work it's a decent solution. We’ll occasionally send you account related emails. We solve problems. Hopefully this can be fixed. WSL 2 will soon be officially available as part of Windows 10, ... and in the latest Windows Insiders slow ring preview build you will temporarily need to manually install the Linux kernel, ... My windows insider machine is a virtual machine running on hyper-v. #4901 (comment). Hyper-V manager will download an Ubuntu image and set up the virtual machine. We will still support the Hyper-V backend until Microsoft stops supporting Windows versions without WSL 2 though, but only as a fallback mechanism. WSL 2 isn’t a mere version bump. Run your docker-compose.yml or w/e up from the Ubuntu (Linux distro) WSL 2 and it goes much faster. Open another Hyper tab with Ctrl+Shift+t, this will show the bash terminal for WSL now. 220mb down 30mb up normally but only. If you found a method to set it permanently (or a script), do share with us. so if it said something like, (Although i didnt get my regular 10 mbps download speed on wsl it improved significantly. The request flow should be really faster than it is now. Getting about 7Mbit/s on WSL2 and 30+ in Windows. apt-get update/upgrade/install downloads packages at unacceptably slow speeds. Thank you! When the next build is released I will test it again too see if it got faster. I have upgraded to build 18956, but it's still slow. I transfered everything inside my WSL's home directory and that fixed it for me. Few Hyper-V topics burn up the Internet quite like “performance”. Earlier this year, we released a technical previewof our vision for the future of Docker development on Windows using WSL 2. Anyway, I think your opinion is correct. Same here, really annoying. If your primary filesystem for Docker "work" (let's say a build) is on NTFS, then Windows Docker is a much better fit until filesystem perf improves. I think it's useful to let people know that this doesn't happen to everyone, I'm getting my full speed here in WSL 2 on Windows 10 2004 (non Insider). While it uses the Hyper-V services of Windows 10, WSL 2 is still not a traditional VM but rather a lightweight utility VM. Running docker on Ubuntu 18.04.2 LTS (WSL Enabled), https://docs.microsoft.com/en-us/windows/wsl/compare-versions, [wsl2] filesystem performance is much slower than wsl1 in /mnt. Why is this closed? To set WSL2 as the default for all WSL distributions, run the following command: wsl --set-default-version 2. We work with technology. The upload is matching. To re-enable Hyper-V, issue the following command: bcdedit /set hypervisorlaunchtype auto. Seems like download speed remained rather intact, however upload was heavily hit. Because I'm making requests (I tested returns only one string) API that take a certain 6s.... =/, @garbinmarcelo Just place your code inside WSL's home directory. The upload is still about only 1/10 of the actual limit, but the download is up-to-standard now. Have u tried this? Disabling Hyper-v worked for me: Select change adapter options. In this article I will tell how to make work with command prompt on Windows 10 better with Windows Subsystem for Linux, Hyper terminal, oh-my-zsh framework for zsh and zsh-syntax-highlighting plugin.. For this article you need to have Windows 10 x64 Version 1607 Build 14393 or higher and installed Node.js.. --------------------------------------- This guy fixed the Ubuntu slow console frame buffer problem for Hyper-V and Ubuntu 10.04. Just FYI. This will disable Hyper-V during the boot phase of Windows 10. Reverting back to WSL1... @pdmwu Are you using Docker For Windows with that WSL integration feature? Ubuntu on WSL. to go faster you need to move your code into WSL distro say into ~/projects/my-project after that you can access your code by cd into you project folder inside WSL and run these two commands: See it in action in this video by Scott Hanselman @shanselman. As the people here are saying. Properly configured Docker and Windows WSL2 will give you really good performance in terms of speed. Estimated reading time: 7 minutes. But not particularly on the internet, it's more on Windows to Ubuntu via localhost access, Windows Version: 2004 Thanks guy! But come on, Microsoft, I really hope you can fix it soon. I use Docker for Windows which works amazingly and has it good perf but sometimes I want to test on a full Ubuntu Desktop.. ASIDE: No joke.My Linux/Ubuntu bona fides go back a while. We will replace the Hyper-V VM we currently use by a WSL 2 integration package. By default, Hyper-V does a decent job allocating appropriate CPU, RAM, hard-disk space, and other hardware resources. Especially upload speed was drastically reduced - 36.61 -> 3.85 Mbit/s. Will try disabling Hyper V thanks @plokko I thought that was not used anymore but didn't think that it might slow down IO. Today is a testing day for me and I finally gave up WSL2 and went back to WSL1. Create a network mapped drive for \wsl$\Ubuntu for example. Even if speedtest is wrong, my download speed in my WSL2 Docker containers is only a fraction of my total bandwidth, so something is still going on. With Hyper-V I was compiling a project in about 5 minutes, now with WSL2 the operation takes about half an hour. Super slow upload speed while using WSL2, and my upload speed on Windows is over 200 Mbit/s. a) First I disabled the WSL2 integration in Docker so it would switch back to Hyper-V. Then I did docker-compose up -d in Powershell instead of the WSL console. privacy statement. Thank you! In order to access your code from Windows Explorer (to open it on a IDE, text editor etc), just go to \\wsl$. WSL has become a popular choice tool of developmnet in Windows 10. People who are still having speed issues even after disabling the "Large Send Offload" options, try changing your DNS configuration for your WSL 2 distro, did the trick for me (I switched to my PiHole). Like... really, really slow. I don't know if this is now an issue with WSL or Docker for Windows. I will keep an eye issues #4197 and this one too see if somebody has found a solution. Edit: Just installed a WSL1 Ubuntu 20.04 LTS and I got 193.61 mbps down / 16.94 mbps up. May be the end of using WSL2 for me as a result. https://www.youtube.com/watch?v=9Q5Ors94lJM. There are huge different on this. It’s faster, more versatile, … No matter how fast it goes, we always want it to go faster. I have not been able to make heads or tails of this. It failed again. Install Hyper.js terminal — https://hyper.is/ I went for the hyper-material-theme to set it up press Ctrl + , to bring up Hyper.js configuration file. I also removed the resolv.conf file and let WSL2 regenerate its own file. Earlier on August 2, 2016, Microsoft released Windows Subsystem for Linux (WSL), enabling the native way to run Linux Tools in Windows 10 and Windows Server 2019. (Replace with name of distro e.g. Successfully merging a pull request may close this issue. I was running a Canary build too, which is the latest semi-stable pre-release. Even more odd, when I spin up a speedtest container, I get 200mbps down/20mbps up. Hyper can be a bit slow, but is most accurate for me. I have my github projects folder in another drive so that was the only option. Tried ConEmu and Hyper. Hosted by CCleaner (Paris) [7.92 km]: 11.246 ms. Install Windows Subsystem for Linux I haven't tested it yet. I stumbled upon https://docs.microsoft.com/en-us/windows/wsl/compare-versions and discovered that WSL2 is actually slower than WSL1 if your project files are on the Windows file system. Turn on the Virtual Machine Platform in your Windows features. I find it personally quite useful being able to do native Linux development onthe Windows partition of my ThinkPad, whilst still having access to all of thenative Windows applications that I sometimes n… Regardless of which version of WSL you want to use you first need to enable it.

Didn't know vSwitch could caused network performance issue. Sign in Switching from WSL1 to WSL2. Here is a test I did on WSL2 and WSL1, I put an ISO file for local download, clearly the speed is an issue, not to mention when I tunnel, it's double down the speed. ConEmu vs Hyper vs Terminus vs MobaXTerm Terminator vs Ubuntu WSL About 2 months ago I started using Hyper but after really getting a chance to use it, I found it to be unusable, at least on Windows. Testing download speed................................................................................ Download: 182.82 Mbit/s Testing upload speed...................................................................................................... Upload: 3.83 Mbit/s. Hyper-V manager will download an Ubuntu image and set up the virtual machine. Everytime I try to boot it, it becomes really slow and doesn't make it past the boot loading screen. Quick orientation with the Hyper terminal keyboard shortcuts: Ouch! Install the WSL2 kernel. Hyper is slow. However, that flag would flip back to enabled by itself sometimes. However, the guest is not stable. Also I had to update VMWare Workstation to latest version 15.5.6 (from 15.5.1) for it to able to start VM. Very slow how to fix? ), now in WSL Ubuntu Ver. We received lots of feedback from Windows Insiders via different channels, and collated common failure cases. Did they improve Hyper-V or did they stop using a virtual machine and create some magic to run the Linux kernel in parallel? For now I will settle down with WSL1 with its reliability and also cross platform of filesystem. I think it's not possible, once shut down and start windows 10, the network adapter is not there until WSL is running. very slow, even if I run docker/getting-started, it stuck 10 minutes no responses. I was surprised to see the comments about only seeing 1 CPU socket on dual Xeon systems too. Update each distro from the command prompt. Let’s use Docker with WSL 1 since Microsoft recommends using WSL 1 to avoid slow file system IO. @rg9400 For those who are seeing download speed hits in docker containers running via WSL2, I discovered today it does not play well over WiFi. WSL 2 isn’t a mere version bump. Script to run WSL, set LSO off, restart WSL again. Solved by following this comment from above! I've capture the video and sharing with you all. @LiamKarlMitchell no, it's still very slow. Dallas Few Hyper-V topics burn up the Internet quite like “performance”. I tried all the suggestions and no luck. So I went back to Docker for Windows.
