[zeromq-dev] New faster 0MQ bindings for Lua & LuaJIT2

[Pieter Hintjens]

Robert, 6M msg/second from Lua, up from 1.3M/sec! Very nice indeed.

Feel free to update http://www.zeromq.org/bindings:lua.

I'd advise you also to put these performance results into your README,
so it's clear to visitors to the project why they want it.
