Go up one level in this thread


The hash table calculation was a guide for use on PC's with older processors.

One should make the hash table as large as possible, that means without Windows
*continuing* to swap to the HD. If that doesn't happen, there's noting wrong
with having big hash tables.

In most cases and move big hash tables will only fill up to maybe 20%, but
sometimes the engine takes longer to search and then it can use bigger HT for
storage of more moves and extensions.

Start the engine, e.g. with the command Alt-F2, listen if Windows starts
clearing memory (i.e. swapping to HD to store),wait till it silences, then stop
the engine and start it again.
If at this time windows remains quiet, there will be probably no swapping and
you have the biggest HT size available without the drawback of swapping, and
with enough spave for the engine itself cached in memory.
