Like with prior Windows Subsystem for Linux benchmarking on Phoronix, for the pure CPU-focused benchmarking WSL2 can provide performance nearly the same as running Linux bare metal on the system.

But for some areas like video encoding there can be upsets where the WSL2 performance on Ubuntu 22.04 LTS was a ways behind the bare metal Linux results... This in part likely comes down to CPU frequency scaling differences between within Windows 11 / WSL2 and Ubuntu Linux itself, given with these same workloads it's also where we have seen some noticeable differences when comparing CPU frequency scaling drivers/governors.
