RE: Long IO Latency

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?
