Is the limiting factor CPU?

If it isn't (i.e. you're blocking on IO to/from a web service) then the
GIL won't get in your way.

If it is, then run as many parallel *processes* as you have cores/CPUs
(assuming you're designing an application that can have multiple
instances running in parallel so that you can run over multiple servers
anyway).
