And the reason why they are different will indicate which one is more accurate, though that higher level of accuracy is still relative to the one that is specifically inaccurate, hence The sys.dm_os_wait_stats DMV is the equivalent of the database consistency check DBCC SQLPERF(WAITSTATS) command in SQL Server 2000.

How To Find Cpu Utilization In Sql Server After I have collected data from either sp_trace stored procedures or the SQL Server Profiler, I generally use a database, which is populated with trace data either after the fact or Because of the I/O speed differences, retrieving data from disk is much more costly than retrieving data from memory. SQL Server manages when and how disk I/O is performed, but the Windows operating system performs the underlying I/O operations.
It's typical, and should be expected, that you will see spikes up to 100 percent at times even when the server is not operating with 80 percent utilization.
