Hi Andrew,

Lately I've noticed that running make -j4 on my quad-core win7-x64
machine causes it to become sluggish or even unresponsive. For example,
compiling a large package makes the mouse jumpy, delays keystrokes, adds
stutter to my music, and makes task switching painfully slow (though,
oddly, if I manage to switch to the mintty that runs make the machine
"comes back"). The sluggishness always hits when I'm using a native
windows app with the compile running in the background. This starts to
sound oddly like the recently-reported issue where X was causing native
windows apps to freeze [1].
I'm glad to hear it's not just me. I've been struggling with this for a few
months, on my WinXP SP3 (32-bit, dual-core) host. I avoid compiling on it,
because after a few minutes CPU goes to 100% even after I exit all Cygwin
processes, and once that happens the only solution is to reboot... which I
usually do with the reset button, because by that point everything is so slow
that even rebooting takes 15 minutes.
There's no PCA or Superfetch service on my host. I'll try shutting down other
services to see if that helps.
Look for the Application Compatibility Toolkit (ACT) as described at:
http://support.microsoft.com/kb/294895
removing it helps some computers a lot.
Another program that causes problems on some computers is the MS Office
2010 Click-to-Run system. It's usually associated with the trial
version. With this system, software is downloaded and installed
dynamically as it is used. Hangs and slowdowns when logging off or
rebooting were noted. Removing this will help. If MSO is needed, the DVD
version can be installed.
Also removing .NET and re-installing it can help some computers.
