Hello,

someone is hosting his forum on my server, it's a ikonboard.
my server had a lot of downtime lately, and I discovered ikonboard was causing it. when I did a "top" I saw sometimes a single request could take up 57% of the processor, 20% of RAM (it's a cheap dedicated server, with only 32mb ram) - so you can imagine, that since his site has 1000 visitors a day, it could get ugly...
since vBulletin is using mySQL instead of textfiles, I'm guessing this problem will not occur with it?
how are the queries optimized? I read some code of free forums (esp. blazeboard) in PHP and mySQL, and usually, they don't use joins but do query's inside loops and real ugly things like that... is vBulletin's code better?

thanks

It would be best to ask this question at http://www.vbulletin.com.

I was using Ikonboard at my site before I switched to vBulletin, and I must say, I found vBulletin light years faster than iB, so I know it had to make the server feel better, too.

While vBulletin is a lot more optimized than most of the other forums, no active board can run well on 32mb ram. MySQL relies particularly heavily on RAM, though I don't know if it will use more than flatfiles. If you possibly can I would recommend an upgrade to 64/128mb or more - then vB would be fine I expect.

I don't know the specifics so it may well run fine on your 32mb server - but it could certainly use more ram.

If you want to see our queries than you simply need to add &explain=1 to any vbulletin forum url. You will find they we always use joins. Querying in loops would just be bad.

Thanks,

JamesUs : I know, but besides this one site my webserver is mostly used for research...

Freddie : hmmm, I took a look, and I noticed there were still a lot of queries... I don't really know the system, what vBulletin can and can not do (all I ever wrote was this little forum : www.ontspoord.com/?module=forum - mind you, it has "bbcodes" with regular expressions and stuff

), but I do believe it could be even more optimized than it is now... but off course, I could be wrong

It is not a VB3 engine, just a parsed copy!
