Cygwin introduces quite a bit of latency, and Windows is slow to start
with.

If you want to spend a fair amount of time on this, I would advise
developing a true Windows port of the tools, rather than using Cygwin.
The mingw32 stuff might help here--I haven't looked at it in a while.
You should plan carefully, and probably consult with the developers,
in order to get your patches back into the mainline cleanly.

Other than that well-understood inefficiency, there aren't any compile
time options which will help you.  We'd all like to use the gcc
-frun-faster option, but unfortunately it hasn't been implemented yet.

There may well be slow spots in the code which profiling will uncover,
and I encourage you to use it.
