What profiling have you done to support that? For example, one of the issues I had which looked like IO performance was actually because the controller was completely unhappy. Upgrading the firmware on the controller card signficantly increased performance. But I think you need to post some further information about the problem. "IO" can be rooted in a lot of issues. :) Adrian
