The claim US WEST is making, or made since I doubt they still believe it, is that the software itself, in the process of all those fun FFT calculations, was tying up the processor. We all know it only takes idle time, but when you look at performance monitor in NT, all you see is that

Given two programs, one running at normal priority, the other at the lowest possible priority (idle priority), the second program will get around 1-2% of the CPU, I noticed the same thing under Linux (with rc5des). Idle processes get a few % cpu time even on perfectly busy systems. You might
