Subject: Querying v$ tables very slow after upgrade

After upgrading our production database from 9.2.0.7 to 10.2.0.3 yesterday we are having severe performance problems when trying to query any dba_* view or v$* view.

I checked and stats were gathered for all SYS tables during the upgrade, the last_analyzed date is the time of the upgrade.

Does anyone have any experience with this?

Thanks,

Patty
