[3.3.x] Support Forum • Re: How to optimize forums to avoid database CPU saturation?

I woiuld 100% turn off all extensions first. Its a very simple first test and you can easily re-enable them.
Some things that have affected the performance of my sites:

* Extensions
* Sessions - check load settings - session length. If its a really long period of time, session table could be huge. Reduce it and then purge all sessions to clear them. (Users will need to log back in.)
* Bots - this one was huge for me, with some bots using huge amounts of system resources crawling the site. I added the following bad bots to my htaccess file:

BrowserMatchNoCase "libwww-perl" bad_bot
BrowserMatchNoCase "wget" bad_bot
BrowserMatchNoCase "LieBaoFast" bad_bot
BrowserMatchNoCase "Mb2345Browser" bad_bot
