We experienced the same problems at my work where dual P3 Xeons running at 1.133Mhz (Compaq Proliants) outperformed a SunFire280R 2:1 in I/O performance. This means that the Proliant had twice more throughput than the 5x more expensive Sun. I don't understand this and I have no explanation from Sun nor from anybody else. I'd hate to say this but Sun is on it's way out if this is the case.
