I've been reviewing the sample Performance Audit
report on Steve Adam's web site
(http://www.ixora.com.au/services/dmop.doc) and trying
to determine the source for the various statistics
presented in the report. In the report, Steve
presents a breakdown of a system's response time by
I/O, CPU, Waits, and Latency. At first glance this
seemed straight forward enough, but after a few trys I
became a little confused. I assume there is a
straight forward way of doing this and I'm just
getting hung up on the terminology.
Would someone please explain how to correctly calculate Disk I/O and CPU Time as a percentage of a system's overall response time.
