The neatest thing about Grok is that it is pure Java with no native code, so it should run on any platform that supports JDK 1.1 or higher. Lots of people have asked about Grok's search speed, probably wondering if reasonable performance is possible with Java. Grok averages around 25 knps in most middlegames on my K6-300. Give credit to Microsoft for writing a very fast Java VM and "just-in-time" compiler. I was using Sun's VM + Symantec's JIT until a couple of months ago, when I finally tested Microsoft's stuff and realized it was 30% faster. 25 knps is still not too great, but I can live with it. (Grok is ~50% faster on a PII-400, presumably aided by the faster L2 cache.) How about the rest of the U2600 members? How fast do you search?

I'm just not interested in playing lots of Crafty clones. Thanks for organizing this club, Will - it's a lot of fun! --Peter
