A question to be asked: Are you using the Lua C API for exposing
functions to scripts, or are you using FFI? The former is RIDICULOUSLY
slow; the latter is nearly as fast as if you had made the same call in
C.
contrary to common repeated advice, the C API is _not_ slow in LuaJIT.
It's just as fast as it is in plain Lua.
Of course, FFI is far faster, but sometimes it's even faster to
manipulate FFI structs with Lua code, especially if you attach methods
with ffi.metatype()
