Satellite 5.7 performance issues after upgrade

Has anyone notice a drop in performance after upgrading to the Satellete 5.7 from 5.6? i get a big lag in time, from scheduling a task
and the time it takes to show up in under scheduling as a pending action. Also, I have noticed a client shows up in pending actions, but
when I go on the server and to a rhn_check -v. The command completes with nothing to report, yet on the web UI still shows up in pending
actions. It seems to me it might be a database performance issue, as it was an upgrade from PostgresSQL 8.4 to 9.2.

For the community are there any peformance tools for Satellite 5.7 or PostgresSQL 9.2 tuning settings for Satellite?
