Is there any stable/tested version of epoll reactor?
Where could we get it?
I would love to get my hands on it!

An epoll-based reactor would probably help significantly in this case.
Also note that Twisted 2.x had some algorithmic speed improvements over
1.3 and should scale better (though that doesn't help with poll() being
