I recently installed WSL 2. I noticed that `@time_imports` reports faster import times for `Preferences` and `GR` under WSL2 than under Windows. The loading time for Preferences.jl is appears to be 10x worse.

```julia
# WSL 2
julia> @time_imports using GR
     24.3 ms Preferences
     90.1 ms GR 4.56% compilation time

```

```julia
# Windows
julia> @time_imports using GR
    263.1 ms Preferences
    162.5 ms GR 4.22% compilation time

```

That’s somewhat surprising. One possibility is that NTFS is a really slow file system, but it would be good to know if there was another reason.

I suspect it is likely a persistent issue from an earlier report that I made:

I can not repro this:

Windows:

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

```

WSL:

```julia
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.

@kristoffer.carlsson did you try WSL (as you said) or WSL2 (as @mkitti) said? i believe it should be a big difference (WSL2 faster than WSL).

At first glance I’m not sure that there’s actually an issue here, considering that comparing package loading on different OS-es feels like comparing apples to oranges. The functionality that’s being loaded is not the same.
