Great! Have you found any way to improve the performance of commands like 'ls'
against remotely mounted file systems? I frequently have things like

 NET USE * \\SERVER\SHARE

where SERVER is located on the far end of a PPTP link to a system a few
thousand miles (18-22 hops over the Internet via an ISDN connection on my end)
and doing an 'ls' is unuseably slow (and I think I've tried various releases
from b17 to b20.1). So, I usually try to remember to use the "command prompt"
and the DIR command which works just fine. I also wave perl scripts over the
remote directories (scripts that do file globbing and file system traversals)
and they run fine...but they don't try to get all the file info that an 'ls
-l' would - ought to try out an 'ls' command from the Perl Power Tools set
sometime...

At any rate...since 'ls' is hardwired into my fingers and I wander into these
directories often enough, using cygwin can be painful, so I haven't gotten
fully into playing with it yet.

That would be useful info!
