  • Your Windows build number: (Type ver at a Windows Command Prompt)
Microsoft Windows [Version 10.0.19041.264]

  • What's wrong / what should be happening instead:
  1. Is it expected to spend so long to active UMIP?
  2. Do we really need UMIP on WSL2?
  3. Is there any way to disable UMIP currently?
@onomatopellan

You can try to add clearcpuid=514 as a kernel boot option to disable UMIP support.

Following this you can add the kernel parameter to .wslconfig as kernelCommandLine=clearcpuid=514

Remember to wsl.exe --shutdown every time you change the values.

After disable the UMIP, I found the problem is not UMIP...

Interesting. Try reducing the number of processors on .wslconfig

I set kernelCommandLine=clearcpuid=514 and processors=8 in .wslconfig and now it takes 1.6sec to boot up with my Ryzen 3700X.

not sure why it's still slower then laptop, but at least acceptable now.

You can also try to compile latest kernel. I'd read it wasn't until kernel 4.21.x that linux wasn't optimized for zen2 CPUs.

Thing is, the delay is going to be an upstream thing; either in the kernel, or some suboptimal interaction with the hypervisor. Someone especially motivated would have to try booting Linux on bare metal to see if the wait is hypervisor related or just the kernel (I give evens). Whatever the cause, the inconvenient truth is it probably won't get many eyeballs in this venue. You could try posting an issue in the kernel github in the hope it might get a sighting.

This may be a problem related to the hypervisor.
