Do you mean your application is working 2.5x - 3x slower?
On the Performance page of the Windows Task Manager a CPU Usage can not be greater than 100%. How did you get'250-300%' numbers?
Thanks for the note. Please take into account that Intel IPP library is not designed for Real-Time applications.
It is 'OpenMP-Threaded' and all OpenMP threads work with 'Normal' priorities and they could be preemted from
executioncompletely by some 'Real-Time' process or thread. Even if I have a couple of test-cases with IPP functions
that could work when a process priority is set toReal-Time I don't use it in real applications. I didn't see significant
performance improvements in my test-cases I've mentioned.
Did you try 'Above Normal' or 'High' process priorities?
