I have changed settings to take advantage of the memory. So the following settings are of interest:
shared_buffers = 16384
wal_buffers = 256
sort_mem = 16384
vacuum_mem = 32768

As somebody else has already pointed out, your sort_mem is bit too high
than required. Try lowering it.

Secondly did you tune effective_cache_size?

I dropped the size of the sort_mem down to 8 megs. Since I am not swapping to cache at all this should not post much of a problem at that value.

effective_cache_size seems interesting, though the description is somewhat lacking. Is this related to the swap partition and how much of it will be used by PostgreSQL? If I am correct, this should be fairly low?
