IPP static libs make huge CPU load

Hi all,

I use IPP 7.1 to process uncompressed images from IP-cam.

So, I have to init my custom DLL, call IPP functions via my own functions inside my DLL and, finally, shut down my DLL.

And of course I have to call IPP functions in accordance with IP-cam FPS. If IP-cam gives me 25 FPS, I have to call IPP-functions 25 times per second.

Everything was fine, when I used dynamic-linkage DLL (as I know, they are multithreaded, so I use ippSetNumThreads(1) to avoid problems in OpenMP). 

But when I tried static linkage, I got huge CPU load. ippStaticInit() call doesn't change anything.

Have I make any additional settings to make CPU load with static and dynamic linkage equal?

Best Regards,

Roman
