Subject: Hash Table Size Versus Performance.

How much does hash table size effect performance?

On one hand we hear that Fritz5 can gain about 40 ELO points by
increasing the hash size from 44MB to 100MB.

On the other hand there are claims that doubling the hash size will
only improve performance by a few ELO points.

I assume the above claims are based on tournament time controls.

So which is the real picture, or is it perhaps that the sensitivity of
size on performance varies from program to program.
