Being async, a twisted server can only make use of a single processor.
With dual core chips, it can only use one of the cores.
No matter what hardware you throw at it, you'll eventually max out that
If you're planning to scale out a lot more, you'll want to structure
things so you can load balance several (1 process per core) twisted
processes running the service.
