You should have chosen a better foundation. pg_bench is notorious for producing results that are (a) nonrepeatable and (b) not relevant to a wide variety of situations. All it really tells you about is the efficiency of a large number of updates to a small number of rows. I'd take the results with a large grain of salt. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
