WSL2 cold start super slow (almost 1 minute) #10966

Closed imag0r closed 2 months ago

imag0r commented 10 months ago

Windows Version

Microsoft Windows [Version 10.0.22631.2861]

WSL Version

2.0.0.0

Are you using WSL 1 or WSL 2?

Kernel Version

5.15.123.1-1

Distro Version

Debian Testing, Kali Rolling, both up to date

Other Software

Windows Terminal 1.18.3181.0

Repro Steps

Make sure WSL is shut down (reboot or run wsl --shutdown) Start WSL2 session in Windows Terminal

Expected Behavior

WSL starts immediately

Actual Behavior

WSL needs almost a minute to start the first session. Once the first session starts, opening new WSL windows is instantaneous, even if starting different distro. dmesg indicates a significant delay between network and memory related messages.

If you use dropcache instead of gradual do you still have the problem?

imag0r commented 9 months ago

No difference. dmesg looks pretty much the same: [ 1.747028] EXT4-fs (sdc): mounted filesystem with ordered data mode. Opts: discard,errors=remount-ro,data=ordered. Quota mode: none.

Actually, I'm seeing the same behavior after commenting out all flags from the experimental section.

@imag0r: Can you capture /logs after updating via: wsl --update --pre-release ?

imag0r commented 2 months ago

Hello, I can no longer reproduce the problem with the pre-release version of WSL.

OneBlue commented 2 months ago

Glad to hear ! Closing
