either. If the Lua code for request handling is only run once,
it's probably not compiled at all. So you're not getting any
benefit from a JIT compiler.
I know, but there are some cases where there are a number of repetitive tasks to be performed, and I just wanted to have these cases covered in case there was nothing to lose for the ordinary cases.
Consider using FastCGI which eliminates the process startup
overhead. And keep the same lua_State alive across many requests,
so the Lua code can get compiled. This should give you much better
I know, but as I need to install in several environments, I'd like to keep most possibilities open (and CGI is the most problematic in terms of performance).
