i hate to say this buy it sounds like your pulling numbers out your ass. The fact is is the PS2 has too many processors to run on our ONE processor. It has the EE, IOP, SPU2, VU0, VU1, GS. All of those have to be running in sync meaning that all the processors just can't go running off on their own. They often have to wait for data being done on a different processor. Most of us are suggesting 4.5GHZ to 6 GHZ just to get normal speed. The overhead of the OS is so minimal, even on windows, that it's almost negligable.
