I just started running the SETI@Home project again after a very long break - basically I ran it years ago on a P2 Xeon 450MHz and it took an eternity.
Now, at work I have a Quad Core (Q6600) XP PC which runs 4 'threads?' at the same time and these take roughly 3-4 hours to complete. A colleague has my old P4 HT 3.0GHz XP PC and that's taking about 6-7 hours.
However, at home I have a dual 2.7GHz G5 PowerMac and the time remaining on the two 'threads' is 17 1/2 hours! I thought the G5 would keep up with at least the P4 and probably closer to the Q6600.
Does the Mac do more work or is the G5 just too slow, because at 17 hours per thread I'd just abandon it on this Mac.
