Why do you need to change the hash size? We really don't
recommend anyone do this under normal circumstances
As it is written in the help, to lower the collisions in 
the case of a lot of concurrent connections. Or am I 
missing something?
not sure how big the collision problem is (have you measured 
an effect?) but Ratz put out the results of a back of the 
envelope calculation that the current value for the hash 
table size would work on the currect fastest machines with 
3G of memory
