The question was "what size hash tables".
4 GB is the total Ram size.
Not sure of hash table setting.
Not sure which operating system was used.
Not sure maximum hash size operating system can manage.
if this machine was getting 3400 kns, then 612,000,000 nodes in three minutes.
so in some positions this machine could fill 512 megs hash in three minutes.
I would think that 1 gig hash would be enough for this machine.
hard to believe that the program and operating system can maintain speed with 2
gig hash setting, but I do not know this.

Robert can you give your opinion on all this?
