I use the Cygwin `ls' with NTEmacs. It is SLOWER because beside looking
in the directory it also READS each file to check for its magic number,
to decide if the file is executable or symbolic link.

I don't think piping is the problem. The spawning is slow (I estimate
it to be 1/3 to 1/2 a second) but it is a constant overhead. The piping
itself is fast (I use it in Cygwin's Bash scripts all the time).

Ehud.
