Hi,
I would like to know if there is any plan or date for WSL2 to incorporate the new Linux patches of the Plan9 Protocol:

https://lwn.net/Articles/918213/

WSL2 performance on Windows shared drives is disastrous (x10 slower). When you carry out compilation processes this is a real problem.

I'm sure it happens to more people. It is the only black point that WSL 2 has compared to version 1.

When is this important advance?

Best Regards,
Abraham.

    Hello there,

    I guess there is no official documentation on this as there are several forums on this topic.

    WSL uses the 9P protocol to share files between Windows and WSL. However, this process only appears starting in WSL 0.70.4. Although there is nothing mentioned about it in the 0.70.4 release notes, the 0.70.5 notes mention fixing a race condition in (what is likely) this component.

    Hope this resolves your Query !!
