You're probably right, but see my comment above: not only is MP possibly superior at being a picking/arbitrating server, but it also supports taking advantage of copy-on-write semantics on Unix-ish systems to transfer memory to children at startup in constant time with no pickling/unpickling necessary.

I agree, multiprocessing will be more performant than ZProc, much more thought has gone into it than the simple 0mq wrapper that is ZProc.

Exactly.
