The vast bulk of this appears to be leading to a reasonable speed increase. One page is running rather slow. The "Search Query Builder". Watch what's going on on the server. MySQL is getting somewhat hammered. Turn on the slow query logging.

SELECT DISTINCT main.* FROM Users main , Principals Principals_1, CachedGroupMembers CachedGroupMembers_2, Groups Groups_3, ACL ACL_4 WHERE ((ACL_4.PrincipalType = Groups_3.Type)) AND ((ACL_4.RightName = 'OwnTicket')) AND ((CachedGroupMembers_2.MemberId = Principals_1.id)) AND ((Groups_3.id = CachedGroupMembers_2.GroupId)) AND ((Principals_1.Disabled = '0')) AND ((Principals_1.PrincipalType = 'User')) AND ((Principals_1.id != '1')) AND ((main.id = Principals_1.id)) AND ((ACL_4.ObjectType = 'RT::Queue') OR (ACL_4.ObjectType = 'RT::System')) AND ((Groups_3.Domain = 'RT::Queue-Role') OR (Groups_3.Domain = 'RT::System-Role')) ORDER BY main.Name ASC;
Hmmm just shy of 7 million rows being queried, for 624 results, that might do it.
