The reason is that IPP performance systemattempts to reach accurate performance measurement (say less than 5% difference in performance between several consecutive calls of function), but it is not always possible due to system activity and other reasons. In that case perf system issue warning which mean that performance measurement was not so accurate.</P> <P>Regards,<BR /> Vladimir</P> Wed, 06 Jun 2007 10:34:37 GMT https://community.intel.com/t5/Intel-Integrated-Performance/ps-ippvc-report-some-wrong/m-p/857596#M7395 Vladimir_Dudnik 2007-06-06T10:34:37Z
