    Phoronix: Windows Subsystem For Linux Performance At The End Of 2019

    Recently I wrapped up some benchmarks looking at the performance of Ubuntu on Microsoft's Windows Subsystem for Linux comparing WSL on Windows 10 Build 18362 (May 2019 Update) and then both WSL and WSL2 performance using the Windows 10 Build 19008 Insider's Preview (what will come as Windows 10 20H1 update) for looking at where the WSL performance is heading. Additionally, looking at the bare metal performance of Ubuntu 18.04 LTS for which the WSL instances were based plus Ubuntu 19.10. As well, for the Windows-compatible tests also looking at how the Windows performance itself was outside of WSL/WSL2.

    Excellent write up and set of test results. Answered some questions I had about WSL/WSL2.

      What are the common use cases with WSL2? Is it to run servers, do scripting or real Linux development?

        Is there a write up about the system configuration or is it a vanilla setup?

        If so how does a vanilla setup compare to a configured system (e.g. vanilla windows vs. windows with windows defender disabled)

        Also did you consider using https://blendermarket.com/products/e-cycles for blender benchmarks, it seems to be better optimized.

          WSL is really windows subsystem for gnu right? (like there is no sshfs,Btrfs,etc.

            Not really. It's implementing linux kernel APIs, not anything from GNU. It alllows running GNU userspace on top of WSL, but that's not WSL itself.

              I think they are mostly targeting web developers who like using *nix tooling.

                It would be much more interesting if we see comparisons between WSL and other VMs like VMWare and Virtualbox

                  I'm still running 1709 at work. Looks like I'm missing out on quite a few performance improvements, let alone WSL2.

                    Yup.
                    Microsoft experienced something new for them, a kind of reversal : lots of (ruby/python/node/etc.) based tools used by devs weren't designed for windows, and well, won't be ported to windows 'cause no one really cares if it works with windows (e.g. "not my fault if your system can't manage long file paths").

                    Funny IMO.
