I am using Windows threading to compute multiple FFTs simultaneously. I have been sharing the FFTSpec across the threads. I am wondering if this could cause a problem or impede performance? Should each thread maintain its own FFTSpec(s)?
I currently have the built-in threading disabled. I get better performance this way, since there is less competition for the processing cores. The platform is WinXP64, 2xQuad 2.6GHz, with IPP 5.3.2.073, em64t.
