Windows is slower than WSL2 in loading GR, Preferences, Julia 1.9.0-beta2

I can not repro this:

Windows:

julia> @time_imports using GR
     13.0 ms  Preferences
...
     46.5 ms  GR 7.82% compilation time

WSL:

julia> @time_imports using GR
     12.1 ms  Preferences
...
     39.0 ms  GR 6.57% compilation time

Can you try clear out .julia/compiled, do a re-precompile and check again.
