Note they ran the benchmark on an Opteron 285 instead of a Xeon with
16 GB of memory. Opteron peformance currently **SUCKS** with 2.6
series kernels under any kind of heavy I/O due to their cloning of the
ancient 82489DX architecture for I/O interrupt access and
performance. Looks like the test was stakced against Linux from the
start. Should have used a Xeon system.
AMD needs to get their crappy I/O performance up to snuff. Looking at
the test parameteres leads me to believe there was a lot of swapping
on a system with already poor I/O performance.
Looks to me like it was the same h/w for Linux as Solaris, so I don't
think that's much of an excuse ;-)
