Disclaimer: I couldn't decide for a subforum to put this in and didn't want to open 2 threads. If someone cares, change it as you like.

Whoever uses a P4 with hyperthreading (and is into the factoring and/or sieving subproject) might consider running a copy of each client simultaneously.

My experience (3 GHz, 800 MHz FSB):

2x sieving = 2x265 kp/s

2x factoring = 83 min / 2 tests = 41.5 min / test


1x sieving + 1x factoring = 265 kp/sec + 62 min / test

Looks like a decent improvement (not considering the effectiveness of factoring vs. sieving).

Any other experiences?
