Recipe 3.3. Enabling Disk Performance StatisticsProblemYou want to monitor disk performance and you need to enable performance statistics. SolutionOn Windows 2000 Server, run the following command and then reboot: > diskperf -y On Windows Server 2003, all disk performance statistics are enabled by default. DiscussionWith Windows NT, both logical and physical disk performance counters were disabled by default. With Windows 2000, physical disk counters were enabled and logical disk counters were disabled. With Windows Server 2003, both logical and physical disk counters are enabled. Logical and physical disk counters were disabled by default in previous versions of the OS because of the concern that the impact to performance would be too great to have them on all the time. As disk access times have steadily improved over the years, the performance hit has become negligible. Now, you can safely have both physical and logical disk counters enabled on either Windows 2000 or Windows Server 2003.
