I think you missed the part where you're supposed to profile your code to
determine exactly where the time is being spent.  For example, it may
be that you can get a big win on typical traffic by running it through
the zlib module to compress the data-stream.  If you have more CPU than
bandwidth.

The gains you might achieve depend largely on what your app is doing,
of course.  If it spends 90% of it's time trying to shove data over the
network, the best improvement you can hope for without reducing the amount
of data you send is 10%, right?
