There are plenty of cases where I get less than 500K nodes per second, particularly if neither side has castled, as I spend a lot of time making sure that I castle when I should, don't castle when I shouldn't, and castle to the right side when castling in either direction is legal. My speed rangd goes from 450K to about 1M. Or on a single Xeon, take 1/4 of the above... > >> >>And no the xeon is not a 64 bit machine. Mine are PII's but with a better >>L2 cache.
