Note that you're likely to get FAR more out of processor affinity with multiple NICs assigned each to its own core / set of cores that share L3 cache and such. Having the nics and maybe RAID controllers and / or fibre channel cards etc on their own set of cores in one group can make a big difference. Processor affinity doesn't seem to make much difference for me with pgsql. Modern linux schendulers are pretty good at keeping things on the same core for a while without predefined affinity. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
