Hello, I come from Oracle world and we are porting all our applications to postgresql.
The application calls 2 stored procs, - first one does a few selects and then an insert - second one does an update The main table on which the insert and the update happens is truncated before every performance test. We are doing about 100 executions of both of these stored proc per second. In Oracle each exec takes about 1millisec whereas in postgres its taking 10millisec and that eventually leads to a queue build up in our application. All indices are in place. The select, insert & update are all single row operations and use the PK. It does not look like any query taking longer but something else. How can I check where is the time being spent? There are no IO waits, so its all on the CPU. btw, postgres and oracle both are installed on the same server, so no differences in env. All suggestions welcome but I am more of looking at tools or any profilers that I can use to find out where is the time being spent because we believe most of our applications will run into similar issues. The version is 9.6 on RHEL 7.2. Many thanks in advance. Regards, Purav
