Scrapping personal :), any interested parties here is the latest (now
"ready" - ehem) tgz: http://luaforge.net/frs/?group_id=265
On OS X and Linux:
make
make test (just to see that it works)
make perftest-plain (a couple of times)
make perftest (a couple of times)
On Win32:
make-mingw or setup-vc; make-vc
lua5.1 -lstrict test.lua
lua5.1 -lstrict perftest.lua -plain -time 1000
lua5.1 -lstrict perftest.lua -time 1000
Current performance figures (perftest.txt):
*** PowerBook G4 1.67 GHz, 1GB
*** Mac OS X 10.4.9 (gcc 4.0.1 -O2)

NOTE: timing on WinXP is inaccurate, the perftool.lua "-time"
option
was used (anyone know of tools similar to *nix 'time'?)

Scrap the personal, I'm interested in that too!

If you have a 4 or 8 core machine in your usage, Lua 5.1 running
on it, and maybe some 5-10 mins of time to spare, give me a
personal reply. Thanks!
