I can't speak for the dev team, but I have noticed a distinct trend:
Apache+mod_perl is very slow with RT4.0.
Lighttpd+FCGI is fast with RT4.0.
Standalone PSGI is really fast with RT4.0 (but not very scalable unless
you know what you're doing).
I haven't tested Apache with anything other than mod_perl, so I don't know
if it's Apache-specific or mod_perl-specific.
Most of the speed problems I've seen posted here are with RHEL/CentOS/SL
stock httpd& mod_perl installs, so it's also possible the problem is
OS-specific.
(And yes, I have a ticket open to try to narrow this down; unfortunately I
haven't had time to keep following up on it.)
Hi, just thought I'd point out my experience, we are currently testing
upgrading RT 3.8.8 to RT 4.0.1.
RT 3.8.8: RHEL5 + Apache + mod_perl + MySQL.
RT 4.0.1: RHEL6 + Apache + mod_perl + MySQL.
~120K tickets, ~13K users, DB ~11GB.
RT 4 is faster than RT3 so far.
Probably the most notable change is setting:
Set($AutocompleteOwners, 1);
Compare the display time "Tickets->New Search"
With AutocompleteOwners: Time to display: 0.442697
Without AutocompleteOwners: Time to display: 17.274538
13K users is quite painful on that page!
Cheers, Jeff.
