General Usage

Could one gain a significant advantage using Julia in Linux running within WSL2 compared to the Windows version?

Package instantiation. 239 dependencies, always starting from blank slate (no depot).

Windows 11 measurements: 452, 521, 505 seconds, mean 492 seconds.
WSL2 measurements: 411, 392, 424 seconds, mean 409 seconds.

Conclusion: It is possible to reduce the instantiation time around 20% with WSL2.

This guy takes a while to compile. Differences in precompilation are small, but favorable to Windows
