https://community.intel.com/t5/Analyzers/Task-Manager-Vs-VTune/m-p/810713#M1872 I am doing profiling of an application. I am using Intel VTune Amplifier XE for profiling. I got that application is taking 3o% of CPU Time which was shown in VTune. And same exe is showing 5% CPU Usage in Task Manager. so, I want to ask that, is there any relation between VTune CPU Time &amp; Task Manager CPU Usage.Please reply soon...<BR /><BR />Thanks in advance<BR />Mayank Prabhakar Tue, 18 Oct 2011 07:04:50 GMT mayankaecgmail_com 2011-10-18T07:04:50Z https://community.intel.com/t5/Analyzers/Task-Manager-Vs-VTune/m-p/810713#M1872 I am doing profiling of an application.

It means there is overhead caused by the product. Meanwhile your application might include many modules, so CPU consumptions from all modules will be counted...<BR /><BR />For lightweight hotspots, ifall active application (system wide) will be monitored and CPU usage is not only for your application.<BR /><BR />Regards, Peter</P> Tue, 18 Oct 2011 08:21:46 GMT https://community.intel.com/t5/Analyzers/Task-Manager-Vs-VTune/m-p/810714#M1873 Peter_W_Intel 2011-10-18T08:21:46Z
