That isn't wholly true. A 4MB hash table can never fit in the cache of an Athlon, and for one that's being used as a workstation with 1GB of ram and maybe 60 connections active on average, that's a huge waste of ram, and a guarantee that there will be lots of cache misses which just aren't required. Keep the cache footprint as low as possible -- it results in a system that performs better.
