Yes, it felt quite slow in certain situations (the last time I’ve tried). Because the WSL works by emulating syscalls from Linux, anything related to I/O can be quite slow...

It's not quite the same as emulation, and the overhead is less. It natively supports these syscalls, and in some cases the syscalls trigger the same code as their windows counterparts

In others, like fork, entirely new and unique code is ran.
