This is from a friend of mine named "sobo"... It is a 2.8GHz P4... I have no other details...

Code:
Best time for 256K FFT length: 9.054 ms.
Best time for 320K FFT length: 11.769 ms.
Best time for 384K FFT length: 14.202 ms.
Best time for 448K FFT length: 17.070 ms.
Best time for 512K FFT length: 19.061 ms.
Best time for 640K FFT length: 24.817 ms.
Best time for 768K FFT length: 30.401 ms.
Best time for 896K FFT length: 37.457 ms.
Best time for 1024K FFT length: 40.532 ms.
Best time for 1280K FFT length: 56.840 ms.
Best time for 1536K FFT length: 70.454 ms.
Best time for 1792K FFT length: 88.189 ms.


Here is my 2GHz P4 for comparison...

Code:
Best time for 256K FFT length: 12.229 ms.
Best time for 320K FFT length: 16.104 ms.
Best time for 384K FFT length: 19.537 ms.
Best time for 448K FFT length: 23.448 ms.
Best time for 512K FFT length: 26.311 ms.
Best time for 640K FFT length: 34.176 ms.
Best time for 768K FFT length: 41.644 ms.
Best time for 896K FFT length: 51.129 ms.
Best time for 1024K FFT length: 55.390 ms.
Best time for 1280K FFT length: 79.667 ms.
Best time for 1536K FFT length: 97.379 ms.
Best time for 1792K FFT length: 121.184 ms.
Hi I am "sobo." For some reasons my benchmarks have improved since I first opened the computer. They are now

Best time for 256K FFT length: 8.670 ms.
Best time for 320K FFT length: 11.491 ms.
Best time for 384K FFT length: 13.949 ms.
Best time for 448K FFT length: 16.736 ms.
Best time for 512K FFT length: 18.750 ms.
Best time for 640K FFT length: 24.405 ms.
Best time for 768K FFT length: 29.892 ms.
Best time for 896K FFT length: 36.509 ms.
Best time for 1024K FFT length: 39.716 ms.
Best time for 1280K FFT length: 55.855 ms.
Best time for 1536K FFT length: 69.355 ms.
Best time for 1792K FFT length: 84.603 ms.

That is almost a 5% increase in speed. I have no idea what caused the increase.
