Before concluding that more threads would be better, you'd have to prove that 
the existing one thread uses all its CPU time. Otherwise, the process is 
I/O-bound, not CPU-bound, and more threads would actually decrease 
performance a bit.

Processing SIP should be a piece of cake, I doubt that the CPU is doing any 
heavy lifting.
