When I click on reply (Update.html), or clicking on a queue from Home
(Listing.html), clicking on a ticket (Display.html) and Clicking on Home
it takes about 15-20 secs longer than it used to on RT2.0.13

what would be an effective number ? I have 4G Memory on a 420R with 4 450Mhz CPU

It is most of the time 96%+ CPU idle and over 2.7 GB free memory. The one that
takes maximum CPU usage is the mysqld ( 7-8% CPU ). With RT2 on same machine it
