Too bad p570 p6 4.7GHz can't beat the Sun T2000 result with the same # of chips and much lower cost!<div>&nbsp;</div> Sun Fire T2000 Oracle Application Server 10g Release - Java Edition with 2 chips (2 systems) did 1871.13 JOPS! Thats 56% faster!

Phil - Thanks for your comment but you really should add that the result you mentioned needed 16 cores, 4 times the number of cores of the systems discussed.

estahl,<div>&nbsp;</div> I agree with your comment and I can add that one should go a step further by looking at the whole system configuration that was used and what was really done to achieve the figures (tuning operations). Compare what is comparable !

IBM System p 570 (4 cores, 2 4.7 GHz POWER6 chips, 2 cores/chip, 16 GB memory) vs. HP rx2600 (4 cores, 2 1.6 GHz Itanium 2 chips, 2 cores/chip, 16 GB memory)<div>&nbsp;</div> Is that not high end IBM vs. HP "entry" level?<div>&nbsp;</div><div>&nbsp;</div> Hardly like for like or apples for apples, is it?

cy - Thanks for your comment. POWER and Itanium systems are often compared. The number of chips, cores, and amount of memory is also the same.
