On June 26, I upgraded all boxes from Suse 7.0 to Suse 7.2 (going from kernel version 2.2.16-40 to 2.4.4-14). Reviewing Oracle job times (jobs range from a few minutes to 10 hours) before and after, performance is almost exactly twice as poor after the upgrade versus before the upgrade. Nothing in the hardware or Oracle configuration has changed on any server. Does anyone have any ideas as to what might cause this?
