Yeah. This was better before the decision was taken to separate bgwriter from checkpointer; before that, only local communication was involved for the bulk of write operations (or at least so we hope). I remain less than convinced that that split was really a great idea. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
