I'm getting rather similar results on my Cygwin 1.7.1, Windows 7 as evidenced
by the figures below. Upgraded from a dual core Windows XP to a quad core i7
Windows 7 causing my cygwin performance to plummet. Even the bash
auto-completion is so annoyingly sluggish that it makes the shell virtually
unusable.
For me, there's no choice between whether or not to make the transition from
XP to 7 as we're using the latest DirectX technology. Hope somebody will
figure this out.
