0. Check your algorithms.
1. Use locals wherever possible.
2. Use LuaJIT.
3. Profile and code the bottlenecks (or have them coded) in C.

Is there a thread or a Wiki entry with the collected wisdom on how to
optimise and speed up Lua scripts? Ages ago, I looked for something like
that and found not a lot. IIRC, I was told that the forthcoming Gems
book will have a chapter about this (done by Roberto, I think).
