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.

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.
Security software is something I don't have.
