No more than any other single-process Python application (no less, either). Unless you run multiple processes... >As far as I know twisted uses one interpreter.

So there's SMP exploitation right there, regardless of whether your Python process is running with Twisted or anything else. > >Has anyone experience high load and twisted? > Distributing load across multiple machines scales better than distributing it over multiple CPUs in a single machine. If you have serious scalability requirements, SMP is a minor step in the wrong direction (unless you're talking about something like 128-way SMP on a supercomputer :) Plus, any solution that works across multiple machines is likely to be trivially adaptable to work across multiple CPUs on a single machine, so when your desktop has a 128-way cell processor in it, you'll still be able to take advantage of it :) Jp -- http://mail.python.org/mailman/listinfo/python-list
