What version of Windows are you running Cygwin on? I'm no expert, but I have
noticed that Cygwin apps run very slowly on Win95 and 98 compared to on NT 4
(I think it may be some screwy difference in the Win9X terminals versus
cmd.exe in NT 4... even running ls on 9X takes a lot longer just scrolling.)
I run Cygwin on a Win98 system with a 650MHz processor and 256 Mb of RAM, and
I also run it on an NT4 system with a 400MHz processor and 128 Mb of RAM, and
_everything_ runs way, way slower on the 98 system. Even compiling a hello
world program takes about 45 seconds on it. If you're on 95 or 98, I'd
suggest giving a shot at NT and see what happens.
