I think "anticipatory" is the default IO scheduler for SuSE 9.3 (from
Google).

It would probably depend on your setup. Given the problem you
describe, tho, I would think that "deadline" would improve your
performance. The 2.6 kernel has many tunable parameters. If you're
pushing a server at all near its limits, you probably need to become
an expert in performance tuning. Or buy more hardware :)
