I'm clueless as to whether it is related or not, but I've been enjoying a similarly bad slowdown on Win32 for about the last four weeks. I wouldn't say that it renders Cygwin totally useless, but it certainly does so for certain tasks which spawn a lot of processes, which is where i think the problem lies. Slowdown after update on Win32 (XP Home) http://cygwin.com/ml/cygwin/2010-09/msg00893.html But it might be a different one than what you are dealing with. Turning on "-x" on the shell clearly shows that the slowdown is due to process creation. Completion is out of the way, as I uninstalled it.
