The custom fields administration screen takes a long time in JIRA 5.1 and the tests show that the database queries performed while loading the custom fields have become 4 times the values shown in JIRA 4.4.5.

With around 750 custom fields it takes around 3 minutes for the ViewCustomFields screen to load.
