Hi Dan,

the fact that you have only a factor 2 to 4 compared to WSL and Debian
tell me that Cygwin is very effective as User space enviroment.


1. time find . >/dev/null
Cygwin 86 seconds
WSL 23 seconds
Debian 19 seconds

2. time find . -ls >/dev/null
Cygwin 129 seconds
WSL 38 seconds
Debian 32 seconds

3. time grep -r -E NOMATCH 2>/dev/null
Cygwin 390 seconds
WSL 144 seconds
Debian 141 seconds

Cygwin can not go faster than the engine below and there are
several cubersome tricks to handle the POSIX compliance

I have seen worst timing trying to emulate  Unix Layer on top of
a not supporting Microsoft environment.

Marco
