[rt-users] any page showing a user drop down in a ticket is loading slow

[Adam Hobaugh]

Hello,

I just updated from 4.0.10 to 4.2.1 and it seems to be working well 
except when I am in a ticket, any page that shows a user drop down, ie 
display and people load incredible slowly. I enabled slow query logging 
and below are the two queries that appear to be causing the problem. I 
appreciate any help in resolving this. 10 second load times is rough. 
Please let me know what further information is needed.

Thanks!
