wsl2 docker performance

This kernel replaces the kernel used in the Linux distributions that are installed into WSL2. The root cause is that Docker uses WSL2 and it has overwritten your previous WSL2 installation. Install Docker Desktop Ubuntu 20.04 vs. Windows 10 WSL/WSL2 Performance In 170+ Benchmarks. Poor network performance in Docker WSL2 MQTT. The performance difference was huge, basic php pages that were taking about 8 seconds on WSL2 were now loading immediately with Hyper-V. To expedite the process of running Ubuntu Linux on Hyper-V, you could set up SSH access to the virtual machine. Form last Docker u p date, Docker engineers added the possibility to use WSL2 technology for boosting performances, giving same development experience on all platform, windows included. All of this is made possible with the recent changes to the architecture of WSL to run within a lightweight virtual machine (VM), which we talked about in an earlier blog post about WSL 2. docker run ~/files:files instead of docker run /mnt/c/files:files for better IO performance Linux filesystem of a distro can be accessed . Do you require a lot of direct Win 10 <-> WSL2 file access (WSL2 has poor file system performance when lots of file activity takes place between the two)? In Ubuntu 20.04: 18000fps In WSL2/Ubuntu 20.04: 100 fps with big delay to see the window In WSL2/Ubuntu 20.04/docker: 700 fps with small delay to see the window What is wrong in my configuration ? If you enable and install WSL-2 on your Windows, in Docker-desktop can use WSL-2 based engine for better performance. WSL2 with Ubuntu 20.04 step-by-step upgrade: getting started on Windows 10 May 2020 Update A detailed guide to upgrade Windows Subsystem for Linux to version 2, aka WSL2, as well as upgrading Ubuntu to 20.04 and leveraging WSL2 for better Docker performance. This speeds up command-line access. Sudo service docker start sudo docker version 5. Have in mind that WSL performance is strictly related to Linux usage, i.e., using WSL to manage and work with your files in /mnt/c won't help. In the most basic of answers: If you're ONLY using docker: WSL2. March 2, 2020 by Matt Hernandez, @fiveisprime Last June, the Docker team announced that they will be investing in getting Docker running with the Windows Subsystem for Linux (WSL). To leverage this as much as possible (and also to get access to the latest build features), you should enable BuildKit by default. Instead, Docker enables the app to use the same Linux kernel as the system that it's running on. Native, results in seconds, lower is better). Instead, you install Docker Desktop on the Windows host, which takes care of exposing Docker to the default WSL2 distro. However, since WSL 2 now runs on a Linux kernel with full system call capacity, Docker can fully run in WSL 2. This means that Linux containers can run natively without emulation, resulting in better performance and interoperability between your Windows and Linux tools. The root cause is that Docker uses WSL2 and it has overwritten your previous WSL2 installation. By slow I mean my sql insert job takes over 5 minutes to run compared with 20 seconds running directly in windows, macOS, or Linux. Oracle 19 in Docker (WSL2) is much slower than a native Oracle 12 install on Windows - Database Administrators Stack Exchange 1 I am attempting to run Oracle 19 inside a Docker container on Windows, but despite the usage of WSL2, I am still seeing an 80% drop in performance as compared to a natively installed Oracle 12 instance on the same machine. Docker Desktop with or without WSL2 activated were extremely slow (~ 12 times slower than native experiments) when sharing docker volumes via the Windows file system. WSL2 has nothing to do with anticheat of course, any VM running on your PC actively affects performance of games, as both consume CPU cores, memory and IO system - you if wanna play just issue wsl --shutdown yes, WSL2 is built on Hyper-V.what would you expect on Windows? And the result was: Docker Desktop running Linux containers on Windows always with great performance . Depending on your system's hardware performance, you likely found that WSL2 is the faster option. from Ubuntu: copy /mnt/c/sources ~/sources) use the docker and docker-compose from your wsl2 distro ( cd ~/sources && docker-compose up. Enable Docker on WSL2 distro - Docker Desktop > Settings > Resources > WSL Integration > Enable integration with additional distros > Check distro. Using Docker in WSL 2. The easiest way to do that is to add the following line to your ~/.profile file: export DOCKER_BUILDKIT=1. Running starting docker volume shares from within the WSL2 context (Shell and file system) can benefit of a significantly faster near-native file access performance. Rodinia benchmark suite results ( WSL2 vs. Take a look at the Docker Documentation concerning WSL2: Best practices. From the Docker menu, select Settings > General. 在WSL2子系统Ubuntu中使用Docker . If you have installed Docker Desktop on a system that supports WSL 2, this option will be enabled by default. If you enable and install WSL-2 on your Windows, in Docker-desktop can use WSL-2 based engine for better performance. The "WSL 2" feature, released as Windows Update in mid 2020, was designed to increase file system performance and support full system call compatibility. Start Docker Desktop from the Windows Start menu. Based on what I read on Docker blogs, I did not expect such a drastic drop in performance when running on WSL2. Professional use of Docker Desktop in large organizations (more than 250 employees or more than $10 million in annual revenue) requires users to have a paid Docker subscription. WSL2 with Ubuntu 20.04 step-by-step upgrade: getting started on Windows 10 May 2020 Update A detailed guide to upgrade Windows Subsystem for Linux to version 2, aka WSL2, as well as upgrading Ubuntu to 20.04 and leveraging WSL2 for better Docker performance. Form last Docker u p date, Docker engineers added the possibility to use WSL2 technology for boosting performances, giving same development experience on all platform, windows included. WSL 2 uses the latest and greatest in virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). We had gain greater than 1400%, which is in line with what was announced by Microsoft of a 20x faster I/O performance in some cases with WSL 2. Windows 10 WSL vs. VirtualBox Ubuntu Performance On An Intel Core i9 7900X. Use Linux filesystem to bind-mount files e.g. As I just mentioned above it seems like using the Hyper V docker backend instead of the WSL2 one seems to help improve the overall system performance. He also has links to other comparisons on the bottom of the page. In this directory create a file named " .wslconfig " in which you will configure how many resources can consume WSL2: [wsl2] memory=900MB #Limits VM memory in WSL 2 to 900MB processors=1 #Makes the WSL 2 VM use one virtual processors Now close your docker and wait for "vmmem" to close in the task manager. For the equivalent MacOS performance issue, the two important things are to not use a bind mount for your application code (just remove the mount altogether and use the code in your image) or your database storage (a named volume works fine). Conclusions From an application running on host OS, I communicate with that broker sending high speed and high size messages. March 2, 2020 by Matt Hernandez, @fiveisprime Last June, the Docker team announced that they will be investing in getting Docker running with the Windows Subsystem for Linux (WSL). Anyone who wants to use nested virtualization understands that it's going to come at a slight performance cost. I observed that the ethernet communication is approssimatively 10x times slower in win than equivalent structure in Ubuntu 20.04. Estimated reading time: 8 minutes. But it shouldn't render the VM un-usable. This article explains why we may have performance issues on Windows, and how to install WSL2 properly for improving performances. Figure 2. I've tried running it by installing it in wsl2 and also under docker running in wsl2. . Docker Desktop with or without WSL2 activated were extremely slow (~ 12 times slower than native experiments) when sharing docker volumes via the Windows file system. Network and storage system performance in particular is greatly improved. First, I setup WSL2 and it was rather slow and I realized that the OpenSuse over WSL was probably swapping, because the processor has a lot of cores, but the 16GB was not enough for it. WSL2 is a virtualised Linux environment that lacks some important features needed by Docker, so you cannot run Docker natively. In both cases performance is terrible. Instead, you install Docker Desktop on the Windows host, which takes care of exposing Docker to the default WSL2 distro. We and our early users have accumulated some experience working with it and are excited to share a few best practices to implement in your Linux container projects! Properly configured Docker and Windows WSL2 will give you really good performance in terms of . Running starting docker volume shares from within the WSL2 context (Shell and file system) can benefit of a significantly faster near-native file access performance. Docker containers are similar to virtual machines, but don't create an entire virtual operating system. In WSL2, they made lots of performance improvement alongside adding new features such as Managed VM, Full Linux Kernel and Full system call compatibility. In WSL2, they made lots of performance improvement alongside adding new features such as Managed VM, Full Linux Kernel and Full system call compatibility. If it is a named volume, you can continue like this. Photo by CHUTTERSNAP on Unsplash It's impossible . 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. If it is a mount from the windows host, you should: move your sources to a wsl2 distro (e.g. All of this is made possible with the recent changes to the architecture of WSL to run within a lightweight virtual machine (VM), which we talked about in an earlier blog post about WSL 2.

I created a docker based on Mosquitto in Win10. Using Docker in WSL 2. Select the Use WSL 2 based engine check box. For testing with Docker Desktop I pulled and run the default Ubuntu image: The latest tag from Ubuntu Dockerhub image is the LTS 18.04: Great, we continue using the same version of Ubuntu for testing. However, WSL2 may still have the upper hand since it does not require SSH to enable access. Hi, I use glxgears in WSL2 and have very poor performance. So basically I open .wslconfig and set processors=2 and swap=0 , it greatly improved performance of the WSL, probably stopped swapping. The performance degradation propagates to the entire system as WSL2 starts taking 100% of the CPU + 100% of it's allowed RAM. Docker Desktop WSL 2 backend has now been available for a few months for Windows 10 insider users and Microsoft just released WSL 2 on the Release Preview channel (which means GA is very close). However, a VM with 8 cores and 32Gb RAM available to it ceases to function properly when using nested virtualization to work with WSL2 or Docker containers. I created a docker based on Mosquitto in Win10. This allows the app package to only require parts not already on the host computer, reducing the package size and improving performance. There are some further notes in the Docker documentation about Docker Desktop WSL2 backend. I updated Windows and Docker and switched on the Docker flag to use wsl2 and was hoping for some performance boost for my Oracle Database running in a Docker container but unfortunately . WSL2 is a virtualised Linux environment that lacks some important features needed by Docker, so you cannot run Docker natively. Solution for Docker performance improvement The suggested solution is: use WSL 2 in Windows 10 and start Docker directly from Ubuntu in Windows Check out the step by step tutorial below. Final Note: The I/O speed compared to WSL 2 and the Docker container, started by Docker Desktop, as expected, showed very close results with a higher average speed for WSL 2. We are very excited about this technology, and we are happy to announce that we are working on a new version of Docker Desktop leveraging WSL 2, with a public preview in . WSL2. However, WSL 2 is not a traditional VM experience. If you require Linux, additional VMs or want access to Docker's Advanced tab for resource allocation: Hyper-V. Poor network performance in Docker WSL2 MQTT. This article explains why we may have performance issues on Windows, and how to install WSL2 properly for improving performances. Share Update to the Docker Desktop terms. WSL2 offers improved performance over version 1 by providing more direct access to the host hardware drivers. Install WSL Because Blender Cycles push a long running kernel on the GPU, the overhead of WSL2 is not visible on any of those benchmarks. CPU Speed - Smaller better I compare below performance on the same computer under Ubuntu directly, under Ubuntu in WLS2 and in Ubuntu docker in WLS2. Docker Desktop WSL 2 backend has access to all your CPU cores. The first one is 3 years old, so only for WSL 1. Docker Desktop. Sudo service docker start sudo docker version 5. To get the best out of the file system performance when bind-mounting files: Store source code and other data that is bind-mounted into Linux containers (i.e., with docker run -v <host-path>:<container-path>) in the Linux filesystem, rather than the Windows filesystem. The second is recent, but only compares to a native install. I am attempting to run Oracle 19 inside a Docker container on Windows, but despite the usage of WSL2, I am still seeing an 80% drop in performance as compared to a natively installed Oracle 12 instance on the same machine. Running Postgres under wsl2 is incredibly slow. Bookmark this question. The "WSL 2" feature, released as Windows Update in mid 2020, was designed to increase file system performance and support full system call compatibility. I observed that the ethernet communication is approssimatively 10x times slower in win . From an application running on host OS, I communicate with that broker sending high speed and high size messages. For the Blender benchmark, WSL2 performance is comparable or close to native Linux (within 1%). I created a docker based on Mosquitto in Win10. Read the information displayed on the screen and enable WSL 2 to continue. The primary reasons to update from WSL 1 to WSL 2 are to: increase file system performance, support full system call compatibility. I observed that the ethernet communication is approssimatively 10x times slower in win than equivalent structure in Ubuntu 20.04. The Docker daemon runs well on it with great performance, and the time it takes from a cold boot to have dockerd running in WSL 2 is around 2 seconds on our developer machines.
