Re: Any quad core users out there? :)

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)

    "make perftest-plain N=1000"	43.56 real   33.70 user  0.47 sys
    "make perftest N=1000"			49.23 real   38.88 user  5.40 sys

    +13% conceived time, +29% CPU cycles


*** MacBook Intel Core Duo 2GHz (black original), 1GB
*** Mac OS X 10.4.9 (gcc 4.0.1 -O2)

    "make perftest-plain N=1000"	14.97 real   14.89 user  0.04 sys
    "make perftest N=1000"			9.71 real    16.23 user  1.14 sys

    -35% conceived time, +16% CPU cycles


*** Fujitsu-Siemens Amilo L1300, Celeron M 1.5 GHz, 512MB
*** Windows XP Home SP2 (MinGW gcc 3.4.2 -O2) (Visual C++ 2005  
Express /O2)

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

    "make perftest-plain N=1000"	17 secs (mingw)	17 secs (VC++)
    "make perftest N=1000"			18-19 secs (mingw) 18-19 secs (VC++)


*** Fujitsu-Siemens Amilo L1300, Celeron M 1.5 GHz, 512MB
*** Ubuntu Linux 7.04 (Feisty Fawn), kernel 2.6.20-15

    "make perftest-plain N=1000"	22.31 elapsed    17.81 user  0.07  
system
    "make perftest N=1000"			23.66 elapsed    18.76 user  0.42 system

    +6% conceived time, +7% CPU cycles
