I'm looking at running session servers in ram. All the data is throw-away data, so my plan is to have a copy of the empty db on the hard drive ready to go, and have a script that just copies it into ram and starts the db there. We're currently IO write bound with fsync=off using a 15k5 seagate SAS drive, so I'm hoping that moving the db into /dev/shm will help quite a bit here.
Does anybody any real world experience here or any words of sage advice before I go off and start testing this? -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
