Hello to all, I am new to this group and postgresql. I am working on a project which uses postgresql and project is time critical. We did all optimization in our project but postgresql seems to be a bottle-neck. To solve this we run the database operations in a different thread. But still, with large volume of data in database the insert operation becomes very slow (ie. to insert 100 records in 5 tables, it takes nearly 3minutes). vacuum analyze helps a bit but performance improvement is not much. We are using the default postgres setting (ie. didn't change postgresql.conf). One more point: When we try to upload a pg_dump of nearly 60K records for 7 tables it took more than 10hrs. System config: Redhat Linux7.2 RAM: 256MB postgres: 7.1.3 connection: ODBC Thanks to all, please consider it even if it is silly doubt. Vivek __________________________________ Do you Yahoo!?
