The same example is run with 1.7, once in Windows 10, and once in WSL2 (on the same machine, of course). The curious thing is the simulation takes roughly the same time, BUT WSL2 is worse running julia code (about a factor of 2), whereas Windows is worse running the Arpack library code (83 vs 106 seconds, ~25%).
Windows 10:
