[rt-users] Slow Ticket History 3.8.8

[Jason Doran]

Hi,
If you are using mysqld have a look at "mysqltuner.pl" perl script  
(google)
This has fixed quickly many performance issues on both RT and other
web-based software we use. I run this every few weeks and apply  
suggested
changes and then simply restart mysqld when things are quite.
