[rt-users] Speeding Up RT by Removing Code to Display File Sizes

[Jason Grigsby]

We've been battling RT speed issues on our server over the past couple 
of months. We had one ticket that took almost three minutes to load 
with 30 transactions on the ticket.

One of our engineers found that removing the code that calculates the 
file size of attachments and transactions significantly sped up our RT 
installation. I've included his email to me below for reference.

I thought this might be of interest to those of you looking for way to 
get better performance out of RT.
