According to Oracle, the average I/O time should be < 20ms for acceptable
performance. I usually see about 5-10ms on my systems - some of which are
RAID10, and some are RAID5 with lots o' cache and a high (.9+) r/w ratio.
50ms is ridiculous speed and 700ms is ludicrous (slow) speed (anyone remember
Spaceballs?)

Just one more question, while reading the I/O latency in the Statspack
report, how slow is slow? I mean lets say the latency is 50ms, how do I
determine that it is slow?
