I leave the firewall and Windows Defender etc on constantly, I haven't experienced any of the issues with speed/IO etc you seem to have. How old is your machine? On a modern computer with a decent processor, a decent amount of RAM and an SSD you really shouldn't notice Windows Defender. Maybe you have more viruses than you think?

It's an i5 3.2ghz quad core with 16GB of RAM and an SSD. Windows defender cripples WSL performance. It's a known issue. Right now most things open nearly instantly and I have no complaints with performance, even when doing very demanding tasks like running a few virtual machines while running test suites and simultaneously recording 1080p video while having 15 tmux sessions running in the background, etc..

  > Windows defender cripples WSL performance. It's a known issue. Hmph. I have a similar setup at home. I haven't noticed anything odd about WSL, but I just use it for development (editing and compiling), but not any heavy-duty processing.

    My main set up is to run Docker for Windows, connect to it through WSL and volume mount code from a drive into Docker to do active development (Rails, Flask, Phoenix apps mostly). While I never ran Windows defender personally, a bunch of my students (I run a Docker course) who had Windows defender enabled said volume performance was disappointing on Windows. After they disabled defender, things were really good. If you Google around there's a lot of people who mention that. Improvements are being made, but I still don't want a tool actively scanning files while I'm trying to use my machine.

  Interesting, I use WSL as well, when I get a chance I'll turn it off and see if WSL speeds up!
