WSL2 is slow and makes my computer unresponsive when running a C++ build in Debug mode inside Docker container

[pksilen]

Windows Version

10.0.19044.4291

WSL Version

2.1.5.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.146.1-2

Distro Version

Ubuntu 22.04

Other Software

Docker 25.0.3
Gcc 13. But this problem has appeared with earlier version of Gcc also.

Repro Steps

Inside a Docker container, compile a C++ project in Debug mode using 'make' command e.g.
make -j 16}; \

Expected Behavior

Normal build that takes a normal time

Actual Behavior

Build is extremely slow and makes the whole computer unresponsive, e.g. trying to start an application takes a long time. However, CPU usage is not close to 100%.

Diagnostic Logs

When I run the same build in Release mode, the build executes in a normal fashion (fast).

When trying to capture the logs, I get the below message. Please advice

Set-ExecutionPolicy : Windows PowerShell updated your execution policy successfully, but the setting is overridden by
a policy defined at a more specific scope.  Due to the override, your shell will retain its current effective
execution policy of RemoteSigned. Type "Get-ExecutionPolicy -List" to view your execution policy settings. For more
information please see "Get-Help Set-ExecutionPolicy".

@pksilen: Which path are you running the build from ? If it's under /mnt/, it's expect that file accesses are slower
