Just wondering is the issue referenced in
http://archives.postgresql.org/pgsql-performance/2005-11/msg00415.php
is still present in 8.4 or if some tunable (or other) made the use of
hyperthreading a non-issue. We're looking to upgrade our servers soon
for performance reasons and am trying to determine if more cpus (no
HT) or less cpus (with HT) are the way to go. Thx
