in thread Use more threads.
I agree completely with what you said about using many threads (or maybe using any threads at all) but what I've written is a proxy checker (with GUI), so most of the time my threads are waiting for a response or a timeout.
My next idea is to see if I can create 100 threads any faster, so I'll tighten it up as much as it is possible, and try that stack_size option. Although my coding is a bit naive and far from professional, my only fear is that I'm inventing the wheel sometimes. he-he.
