A couple of things are strange here:
1. Look at how much slower things progress on my system. I am using a Centrino
1.8 GHz laptop (certainly not a whole lot slower than a 3 GHz P4). Perhaps the
results above had much of the TBs already in RAM from previous accesses to them?
2. At one point, Yace sees an eval of 11.46 and with additional searching it
drops its eval to 4.66 . That was not seen in the post above either.
Can anyone shed some light on why these results are so different?
Thanks,
Roy
