[self-interest] Performance?

[Michael Latta]

I just compared my 1Ghz G4 and my dual 2Ghz G5 and the G5 is slower!  I  
presume that the Self compiler is testing for architecture and the G5  
is failing?

On the G5 I am only getting in the neighborhood of 25M ops/sec and 900k  
sends/sec with the G4 around 14M and 1600k sends/sec.

The latest version of Squeak on the G5 is 133M and 6800k respectively.

It looks like Squeak is catching up!

Any news on what is going on in Sun with Self?

Michael
