Is this CMP or BMP? We're focusing on CMP performance in version 2.3. How are the transactions written? Do you call multiple methods from a client, or are you using session wrappers, or is each transaction one method inherently? Do the update and delete call a finder then loop through the resulting collection, or do the call individual findByPrimaryKey()s? Also, if you can try Postgres 7.1, it should be much faster for various reasons. -danch _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
