What are the things to be measured?
Common term Perfmon Counter name Average IO Size Avg. Disk Bytes / Transfer Average Latency Avg. Disk sec / Transfer Throughput Disk Bytes / sec IOPS Disk Transfers / sec
Latency is normally expressed in milliseconds (ms), but Perfmon does display the value in seconds, for example 0.015 seconds = 15 ms.
Throughput is often expressed in MB/sec, but Perfmon in Windows 2003 displays this in Bytes/second, e.g. 382,090,819 meaning 382 MB/s.
