We've recently upgraded our instance of Moodle from 1.8 to 1.9 (Build 20080423).
A very simple database with 8 text fields and only 12 records takes 12.4 seconds to move between one record and the next one in Single View.
In a slightly larger database of about 50 fields and 120 records, the time is closer to 17s.
The "view" performance of these databases before the upgrade was as fast as browing the module list on this site....
All other aspects and modules of our instances of Moodle are working as fast as they did before the upgrade
Has anyone found a similar problem? Can you suggest how I might troubleshoot the issue to determine the cause of the problem?
