WSL2 on Windows 11 uses the same file translation layer between the host FS and the VM FS as it did on 10, so pretty slow. The big improvement with WSLg is that now you can run desktop linux apps (such as your IDE) within the WSL file world, which should give you near-native FS performance as long as you're not accessing /mnt (and if you want to browse those files on Windows, you can always open \\wsl$ in file explorer).
