I upgraded my Linux box to have 96MB of memory, up from 32MB ($250, who
would have believed _that_ a few years ago).
There is a significant difference in Postgres performance, with the
regression tests taking ~5:15 to complete vs. ~6:20 before the upgrade
for a 17% speed improvement. There is little or no evidence for gross
degradation of performance with repeated runs of the regression test, as
I had reported earlier. So, the conclusion is that more memory is better
(duh!) and that as the buffer gets filled or fragmented smaller memory
machines start swapping.
