CPU benchmark advice

Well, pretty sure I've done 100k battles in a month, so this tells me it's 2.3x as fast. I probably wouldn't shell out $700 for double the Robocode power, but I'm guessing it's much more of a multiplier than that. Also, I reckon performance could scale differently with simple bots (many of your rumble battles) vs high-end bots, which are surely much more memory-intensive, and thus perhaps not as much sped up by an increase in raw CPU power.

So I'd still really love to know the time a certain battle takes and how close to linearly your Robocode power scales with # of cores...
