first, i'd like to say that Luxinia seems to be very interesting! but it's
windows only, so it's useless. it would be far better if that was admitted
in the front page, instead of having to search the requirements and/or look
the download files.
now to your problem. i'm guessing that the performance hit is because you're
calling lua_pushstring() on your hook function. do you really need the file
name on the Lua stack? can't you manage that on the C side? interning
strings is not the fastest Lua operation...
if you really need it on the Lua stack, it might be faster to move around as a
Lua value, so it doesn't have to be interned on each hook call.
