Super Pi

Yes it's HT. Not sure if the ram has got anything to do with it... 1.5GB corsair and the ram is run in dual-channel mode.

I dont think beyond a certain point RAM would matter. I mean its mainly a CPU intensive application. Above a certain threshold RAM size won't matter. Even I think above 512k of L2 cache the differences would be negligible (from cache size perspective).

jsantos@gentoo-laptop:~$ ./super_pi
Version 2.0 of the super_pi for Linux OS
Fortran source program was translated into C program with version 19981204 of
f2c, then generated C source program was optimized manually.
pgcc 3.2-3 with compile option of "-fast -tp px -Mbuiltin -Minline=size:1000 -Mnoframe -Mnobounds -Mcache_align -Mdalign -Mnoreentrant" was used for the
compilation.

Sorry I just had to try this. I upped the CPU core speed from 200 x 15 (3ghz) to 214 x 15 (3.19 ~ 3.2Ghz)

Made a slight bit of a difference.

Much better time without Wine. 46.4 seconds.
