It's not "automatically" obvious, but that doesn't mean that it will 
work.  Develop some benchmarks for your application, see how fast it is, 
determine whether you need to optimize it, and profile it to discover 
which parts would benefit from optimization.

This strategy is not unique to Twisted, Python, or any other library or 
language, for that matter.  Even if you wrote your whole system in C 
there is no guarantee that it would magically be fast enough to support 
your users.

In most cases Python is fast enough, and in those cases where it is not, 
you can usually move just a few functions to C.  I have never seen a 
case where Python was so slow that an entire system needed to be
