Hi, I use PostGreSQL with a Web server which receive 200 HTTP simultaneous queries. For each HTTP query, I have about 5 SELECT queries and 3 UPDATE ones. Queries have been optimized, I have INDEX on my tables... The biggest table has more than 500 000 records. And I have big troubles, PostGreSQL doesn't seem to be able to handle so many queries at the same time. The server is a NetFinity bi-proc 400 MHz with 1Gb RAM... What can I do ?? Thanx in advance Guillaume
