I decided to open this as a separate issue because although it's related to the generic issue of filesystem performance it's directly related to WSL 2 while the other issues are for WSL 1 and it's showing very conflicting results. The performance improvements with WSL2 are largely because this version is running as a privileged virtual machine on to of MS Hyper-V. This kernel has been specially tuned for WSL 2, optimizing for size and performance to provide an amazing Linux experience on Windows. Accessing Windows filesystem from WSL2, when developing is extremely slow. And, of course, the most common place to […], When we are going to buy a new keyboard, there are many who decide on a gaming model, especially if we are passionate about PC […], Search engines like Google are part of our day to day. Have you noticed a difference in the amount of RAM that the WSL2 is able to utilize versus running Linux natively? I was not alone, in the GitHub repo of WSL I found issue 4401 which was quickly pointing to 4197. I'm seeing 249.94mbps down / 15.42mpbs up on Windows, which is pretty much what I expect from my ISP. ... essentially NO, but read on to see what we actually looked at with our tests. I assume you ran numbers several times to check for natural variability ... really it doesn't look too bad to me but it does indeed look like there was a notable effect from the hypervisor running. Thank you for posting that GitHub issue link! WSL 2 using its built in NTFS support (going via the 9p service exposed bythe Window host) is unusably slow. So what? 比较 WSL 1 和 WSL 2 Comparing WSL 1 and WSL 2. There are a few places where there was a performance drop around 2%. WSL (Windows Subsystem for Linux) is a compatibility layer for running Linux binary executables natively on Windows. And this is how WSL came about . For jobs that are not bottle-necked by memory pipeline staging it shouldn't slow things down (may even speed things up) ... wishing you the best --Don. However, with the […], Windows 10 is by far the most widely used operating system in the world for desktops. Some things I've tried or looked into: My files are on the Ubuntu instance in the home folder. The kernel will be serviced by Windows updates, which means you will get the latest security fixes and kernel improvements … Autor: Vanger 11.09.20 - 16:15 WSL 2 bootet ja einen "vollwertigen" Linux-Kernel in einer Hyper-V VM, letztlich basiert WSL 2 also auf einer Vollvirtualisierung mit Linux als Gastsystem, das um diverse Features zur Host-Integration erweitert wurde - neuerdings sogar mit der Möglichkeit Dateisysteme auf dem Hostsystem zu … On Reddit, someone has wanted to share tremendously interesting […], For several generations the Android operating system will allow us to choose between activating or deactivating floating notifications on Android phones . ... First your Windows build number (using PowerShell) (gwmi win32_operatingsystem).buildnumber, Then check your WSL Linux installs (from PowerShell) making sure that your Linux distro installs are using version 2 of WSL wsl -l -v, Then start up a WSL Linux shell and look at a couple of things;Check the kernel version number uname -r, then check the number of CPU's (this should include SMT threads unless you have that disabled in the BIOS) nproc, Then for a more low level view do (the last chunk of this output should be describing the last core/thread and give the processor number [numbering starts at 0]) cat / proc/cpuinfo, For the system I'm on right now (latest insider dev channel build) here is what I see (an Intel 9920X). Even when your parts warranty expires, we continue to answer your questions and even fix your computer with no labor costs. However, all of the results greater than 2% were negative. That is a very interesting thread ... one comment that caught my attention is"Not sure if it is relevant but I am experiencing the same issue in hyper-V too." Awesome mounts performance Both your own WSL 2 distro and docker-desktop run on the same utility VM. We tested to see if there was any negative application performance … Since June 2019, an enhancement of WSL (WSL 2) was delivered with Windows 10. When I first started reading your comment I was thinking "Oh no, it's only using 64GB" I think your analysis of the memory overhead is about right. Linux systems will allow a lot of memory to go to a process but Windows is not quite so generous :-). On WSL2, sppedtest-cli shows 4.69mbps down / 3.29mbps up. That could be a "real" performance drop or just normal variation. This kernel replaces the kernel used in the Linux distributions that are installed into WSL2.

WSL 2 brings a hybrid approach with a lightweight VM, a completely connected experience, and high performance. I am currently using a dual cpu system with 128GB of RAM and when I boot to my Fedora partition and run neofetch, all of the 128GB of RAM is reflected. Ubuntu wins, although for very little. WSL allows us to install a virtual Linux on top of our Windows 10, thanks to Hyper-V, so that we can have access to the Linux terminal and any program for it. They just run in separate namespaces so that they have the illusion of running totally independently. It's just that WSL2 and VirtualMachinePlatform is enabled for comparison. Since I am using Windows for other applications too, I would rather wait for a "stable" version. In addition to looking at the WSL1 vs. WSL2 performance of Ubuntu 18.04, Ubuntu 18.04.2 LTS itself was also tested bare metal on the same system for looking at the raw performance of Ubuntu on the Intel desktop being tested. In this version of WSL, you can make use of the Linux file system itself and makes it much faster during git clones, npm installations, and builds. But with WSL2, it only reflects 102,959MiB or ~108GB of RAM. I got concerned so I used Matlab and Julia (which both have their implementation for parallelization) and they ran fine. Well Microsoft has heard the cries of Linux lovers, and are shipping with an actual, full fledged Linux kernel now! In particular, the Windows feature "VirtualMachinePlatform" must be enabled for WSL2. My "Puget Systems Labs" colleague William George graciously agreed to run our Windows test/benchmark suite on a Windows 10 system with and without WSL2 enabled and active. This means, Docker Desktop only uses the required amount of CPU and memory resources it needs, while enabling CPU and memory-intensive … In this way, it has been possible to verify the good work that Microsoft is doing with its subsystem, although it is still somewhat far from native performance. After a long time considering Linux a cancer and its worst enemy, recently Microsoft has taken a special fondness for this operating system. For this, this portal has used its own benchmark suite, Phoronix Test Suite , with which it has tested the 3 systems with dozens of tests, all of them under the same conditions and circumstances. The Phoronix portal has tested the performance of the old version of WSL, the new WSL2 and an Ubuntu natively installed on a PC in order to check how well the virtualization system of Windows 10 works. The Linux kernel in WSL 2 is built by Microsoft from the latest stable branch, based on the source available at kernel.org. There are things that a few years ago we would never have imagined, for example, that Microsoft was going to start developing open source software, that parts of Windows code were going to be released or that Linux was going to be able to be installed on top of the operating system. WSL 2 is quite new and still rapidly evolving leaving you with a more automated installation procedure at the time I wrote this blog post. This means that at least low level support for the Hyper-V virtualization layer needs to be enabled to use it. Is the overhead of the WSL this large? (like VMware ESXi for example) Your "host" Windows OS is running in a special Virtual Machine on top of that. After enabling the feature you have performance losses in the AIDA64 cache & memory benchmark. So do we know what difference in performance there is between Linux on WSL, WSL2 or natively installed on a hard drive? Happy computing! WSL 2 is powered by a real Linux kernel in a lightweight virtual machine that boots in under two seconds. Starting with Windows Insiders preview build 20211, WSL 2 will be offering a new feature: wsl --mount. At Puget Systems, you can actually talk to a real person! Rather than getting a generic workstation, our systems are designed around your unique workflow and are optimized for the work you do every day. The "Windows Subsystem for Linux", WSL, is one of the most interesting projects that Microsoft has ever implemented (in my opinion). We’ve heard feedback on how many users have enjoyed using WSL 2 and have made WSL 2 available to more Windows users with this backport. And Yes, It seems to be an issue rising from hyper-V and it is affecting WSL2. wsl.exe –install . Sockets performance benchmarks WSL . Recent "Insider Dev Channel" builds of Win10 even allows access to the Windows NVIDIA display driver for GPU computing applications for WSL2 Linux applications! (the current update might not fix the issue ) https://docs.microsoft.com/... Also,Updates to WSL2 (and it's kernel) should come with the normal Windows updates. Where did this amount of RAM went? Ubuntu finished first, that is, it achieved the best results, in 61% of the tests. WSL 2. The following table lists "summary results" for the various benchmarks that were run. Full System Call … I find it makes development work MUCH more pleasant. Customers running Windows 10 version 1903 and 1909 can now enjoy faster file system performance, 100% system call compatibility, and be able to use Docker Desktop with the WSL2-based engine.

WSL 2 does not have traditional virtual machine limitations such as reduced performance and limited resources. It is basically on top of a HyperV VM so there may be overhead there too. Why would enabling "VirtualMachinePlatform" for WSL2 support be a concern? This looks like it may be config bug (or oversight) by the WSL team. 将适用于 Linux 的 Windows 子系统从 WSL 1 升级到 WSL 2 的主要区别和优势是： The primary difference and reasons for updating the Windows Subsystem for Linux from WSL 1 to WSL 2 are to: 提高文件系统性能， increase file system performance,; 支持完全的系统调用兼容性。 Is it possible to test WSL 2 with Ryzen threadripper 3990x, it seems to fail to detect all the cores. Derzeit verwendet Microsoft dabei den Linux-Kernel 4.19 mit Long-Term Support (LTS). Similar to prior Windows 10 releases, WSL2 continues offering much better I/O performance than the original WSL that was one of the main limitations. The loss in the cache benchmark is between 10 and 25%.These are not application scenarios, but I still wanted to mention it. MS has a kernel update guide ... not sure if you want to try this or just wait out an overall update fix. I did my tests with a freshly installed Windows. However, we did not do any direct gaming performance testing! It is WSL2 running Ubuntu: 20.04. The finial performance evaluation is the percent difference of the "with" and "without" result averages. Even if there is a small drop in performance for some applications it is worth the trade-off in my opinion.
