[Freeswitch-dev] mod_lua speed up

[Vicente Hernando]

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.
