Re: Squeezing more performance from the Lua interpreter

[Eduardo Bart <edub4rt@...>]

Thanks for mentioning this, I've used the PGO (profile guided optimization) from GCC through `-fprofile-generate` and `-fprofile-use` flags and got another ~10% relative improvement!

Thus now combiling all the tips from this thread this is my results from the baseline:

Results: 0.706 seconds. (-34.1% from baseline)

Thus I found out that generally my Lua 5.4 is about ~10% faster when running the script compiled with profiled guided optimizations for that same script.

Does anyone have other ideas on how to tune the Lua interpreter to squeeze more performance?

My experience with Visual Studio (on windows) is that rebuilding the sources using profile guided optimization can almost double my program speeds.  Not sure if it would translate to Linux -- but, insomuch as you do have the capacity to do a build that's optimized based on real world usage data, rather than just using a canned heuristic set, I think that's worth trying.
