Hi,

Intel's new processor core 2 duo (c2d) have been getting pretty good reviews. How well is PETSc performance on the c2d?

I wonder how much speed improvement will I get if I upgrade from my current Athlon XP 2400+@2200mhz. Also the speed improvement over my school's xeon 3.06ghz server.

Is there any place where I can get or run some benchmark to get a rough comparison?

Btw, how important is L1/L2 cache impact on PETSc's performance? e.g. 2Mb vs 4 Mb L2 cache different.

Thank you.
