RE: Lua: Performance

["Manish Jain" <manish.jain@...>]

We are using general aspects of Lua
1) Simple constructs like if, for, repeat, gsub, function calls, etc etc
2) we are using very less number of global variables.
3) we have registered few C functions and we are calling them in our lua
module.

Please share tips and tricks so that we can use them.

Best Regards,
Manish Jain

What specific aspects are you having performance troubles with?  Lua is
already among the fastest available scripting languages, but there are
several tips and tricks you can employ to improve the performance of
your code without changing Lua itself.  One common error, for example,
is to assume the performance of globals is good compared to that of
locals.
