Actually, electrons themselves flow rather slowly -- millimeters per second according to Wikipedia. The signal propagation is a bit faster: "typically 75% of light speed", Wikipedia again. Anyway, he means "transaction rate". But the actual useful figure is further removed from that because we're mostly only interested in write transactions, not read-only (though those still have an effect in versions earlier than 8.3.) -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
