Repro Steps

Run WSL for a number of days without restarting, it gets slower and slower.

Today I was really noticing it so ran a test, a refactor I'd been developing which is some shell, perl and golang reported by time:

real    6m51.373s
user    0m21.999s
sys     0m3.586s

After closing wsl and restarting with wsl --shutdown the same thing took:

real    0m42.377s
user    0m34.388s
sys     0m14.403s

Before the restart vmmem was using 22GB of RAM, afterwards 2.3GB

Expected Behavior

WSL should not slow down after time

Actual Behavior

Significant slowdown just be using it for a few days.

Still an issue, and have to regularly restart wsl to address significant slowdown.

Having a bot close an issue because no one replied is counter productive. There should be an option to confirm its still an issue an keep it open.
