RT 3.8.1 merged tickets slow

im using RT 3.8.1, and have googled this issue extensively to no avail.

specs:

RT 3.8.1 migrated from 3.4.5
mysql 5 upgraded from mysql4 with both the RT updates as well as the UPDATE.mysql schema updates applied
apache 2.x

loading a merged ticket takes on the order of 1-2 minutes in some cases. often times fetching a merged ticket results in an apache timeout while waiting on the script.

any suggestions?

lars,
good idea. MySQL query logs show im pulling alot of info from various different tickets (of course, lusers love to merge.) curious if caching might help the situation, as precaching and output buffer adjustments to fcgid are now causing page render’s to be lightning fast.

How many tickets are in your database?

Watch your MySQL query log to see what queries this request is
generating. See if running the same queries by hand (via
mysqlclient)takes just as long. This should at least help
differentiate database
slowness from something else. It’s not a solution, but it
may suggest
where to focus your efforts.

Hi John,

im using RT 3.8.1, and have googled this issue extensively to no avail.

RT 3.8.1 migrated from 3.4.5
mysql 5 upgraded from mysql4 with both the RT updates
as well as the UPDATE.mysql schema updates applied apache 2.x

loading a merged ticket takes on the order of 1-2 minutes in some cases.
often times fetching a merged ticket results in an apache timeout while
waiting on the script.

Maybe it’s this: RT tries to write hundreds of messages to syslog when opening merged tickets …

Try to decrease that using
Set($LogToSyslog , ‘info’);
in RT_SiteConfig.pm
