Hi Michael, the goal for us is to compile only once the lua script ( in our case it performs connections to several redis instances ). I have still not tested it yet, only wanted to know if it was a crazy idea, or was it just plain impossible. When I get the profiling done I will post it here. Kind regards, Vicente.

If you profile this, how long do those actually take? how does that compare to whats needed to clear out a lua state fresh so there is no bleed over to the next usage?

Hello,
looking at src/mod/languages/mod_lua/mod_lua.cpp
I see executing lua_init lua_uninit at the beginning and end of every function, then a lua script is loaded from a buffer, compiled and executed.
Another approach could be loading some lua scripts at the beginning and compile them. Then create a pool of lua states.
Now everytime lua_init is called, instead of initializing lua again, it would take a lua state from the pool if available, otherwise it would create a new one.
lua_uninit would reintegrate a lua state into the pool again.
At the end, when module is finished being used, the whole pool should be freed.
Do you thing it is a worthwhile idea or a crazy idea? Any points?
Thanks in advance, Vicente.
