Side by side results

4CPU version

2CPU version

I will be running more games for all pairings - I stopped them early so I would have both versions in the update.

Oh before someone asks the 1.6s version was the second corrected JA compile.

Yes

29/12/2009 10:12 to be precise.

P.S. The next update should have approx 1700 4CPU games for each version + 1000 1CPU games for each version. My current thought is that with less time/cores the 's' version does better but I do not have enough data for confirmation
