This is an old problem, the last I heard on it was something along the lines of:
"Cygwin's functionality/compatibility/robustness improved in necessary
ways, but performance was required to suffer"
From a hearsay perspective, it appears to be related to fork/exec
performance, and more specifically probably related to proper memory
allocation/management.

I'd say "Try using Colinux", but they haven't gotten their 64 bit act
together yet.  (barely decided they're going to try)

One other time I was frustrated and got 50% improvement using a
smaller shell, (sh) but really that's a drop in the bucket,
performance-wise.
