I have been testing dbench and Andreas elevator work. The test involves
different elvtune parameters and seeing how it affects dbench throughput.
My testing has stopped because of some oopses. :(
There's about 4 of them and I put them all at the bottom of this mail. It
looks like ext2 problem to my fairly untrained eye. Those addresses look
VERY suspect to me aswell: 0101010X?
Andrea: I was running with very low read and write latencies at the time.
(at the time of the oops, I think both read and write latency was 1) I
guess my full table of results will have to wait now ;)
