> Those are some nice numbers, to be sure!  Twisted really benefits from running in a pypy vm.  I have read that pypy still doesn’t optimize old-style classes as efficiently as new-style classes; I wonder if there would be any meaningful change in the metrics if resource.Resource was a new-style class instead of an old-style class.

Yep, using new style classes is indeed recommended for performance on 
PyPy. We are using new style classes throughout Autobahn and 
Crossbar.io, but I haven't measured effects.

You need Linux kernel 3.9+. DragonFly BSD also claims support, but I 
haven't tried. We should also be able to make Windows work, after some 
more things have landed for the Twisted IOCP reactor.
