Title: LuaJIT intergration?
Post by: Herodes on 15 March, 2006, 09:59:49
I am tempted to request the intergration of LuaJIT (http://luajit.luaforge.net/) within PxLua :)
LuaJIT is smth like a speed enhancment to vanilla Lua..
it is also considered to be a project with high future aspirations among the lua community.
So it is not really destined to 'die off in foam' ...
Its perfomance outcomes are summarized below :

QuoteSummary

These results should give you an idea about what speedup you can expect depending on the nature of your Lua code:

  • LuaJIT is really good at (floating-point) math and loops (mandelbrot, pidigits, spectralnorm, partialsums).
  • Function calls (recursive), vararg calls, table lookups (nbody), table iteration and coroutine switching (chameneos, cheapconc) are a lot faster than with plain Lua.
  • It's still pretty good for indexed table access (fannkuch, nsieve) and string processing (fasta, revcomp, knucleotide). But there is room for improvement in a future version.
  • If your application spends most of the time in C code you won't see much of a difference (regexdna, sumfile). Ok, so write more code in pure Lua. :-)
