Still, you should try toying with the MaxHighMemWorkers=n parameter. Set n to 3, and depending on the B1 and B2 sizes (more precisely, the relative durations of Stage 1 and Stage 2), you may almost...

True, but that´s because the FFT is very small, isn´t it? What I am doing now is running 2 workers, 2 threads each. The global throughput is much better.

Additionally, the amount of stage 2 memory used (in MB) for the different B2 values was:

105 * B1 ---- 738

500 * B1 ---- 1159
1000 * B1 ----1778
100 * B1 ---- 9813 ...

Yes, that is right; I just didn´t make myself clear enough: I meant to say that for a given value of B1, in this case 110M, just reducing the value of B2 didn´t seem to be a valid approach. I gave...

Yes, that is certainly the case for ECM Stage 1 on FFTs this small, so P95 runs single threaded. For stage 2, the program uses 3 helpers although the FFT size is probably about the same size, I think...

Even just one instance is currently not allowed. First time it was disconnected after 3min44s, second time after 2min37s. I´ll give it a break for a day or two then try again.
