He explains why he thinks you'll sustain less. Basically it's caching effects because no pg_xlog / wal log writing happening.

Still pretty good numbers so far. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
