We were able to reduce the startup times for a new Lua state from 2-3ms to about 50us, which was pretty dramatic (including loading various private libraries). Of course, you later paid a bit extra for the meltable hits when look-up DID occur for library functions, but in our application where the states were short-lived this tax was acceptable.

How did you solve the problem that modules can be loaded twice, e.g.

local math1 = math; math = nil; local math2 = math

But interesting to hear that we invented the same thing ;)
