Automatically stopping P-1 to benchmark? Why?
 

I am running P-1 on an exponent in the 332M range. Twice so far in the middle of the night Prime95 has stopped to run some benchmark, then continued. This was during stage 1. It was already over 10% in when it stopped the first time.

It said that the benchmarks were needed. Why?

It is trying to figure out which FFT implementation is the fastest for your upcoming LL test.

But, I am only running P-1, not an LL. I was picking off one of the poorly done P-1 from James's website.
