Given that a 1 GHz CPU can do about 100,000 logical I/Os
per second, and the largest machine is currently (I think)
only 128 CPUs, I can only guess three possibilities:
Your instance has been up for the last 500 years
The statistics numbers don't match the ones that the
Oracle code is supposed
Glenn - V$SYSSTAT holds cumulative values since the instance was started.
You need to measure it over a period of time. Note the values, then note
them again in one hour, and measure the difference. Or use Oracle's utility
STATSPACK or the older utlbstat/utlestat. Even better, get Oracle
