MASSIVE serverload at peaktimes!

[marocnl]

Hi there,

Can anybody tell me why the hell when i more than 90 users are online my serverload is acting like it's going crazy. I've measured a serverload of 160. When there r less than 90 (more or less) than it's about 3 or 4.

Can anybody tell me how to fix this?

HELP! It might be to do with settings in your httpd.conf - I know I had this problem myself, but I'm not knowledgeable enough to advise any setting changes...

Hopefully someone can help :) but rest assured it IS fixeable!

Hi there,

Thnx 4 the assurance:), but the problem is that my host-provider already configured a lot, and it just isn't helping. As soon as there is somewhat of activity, like replyin, starting a new thread or whatever, my serverload goes through the roof.

Could you recall what you changed?

Greets It was the minservers and maxservers I think (but don't take my word for it! My host walked me through it:)).

Hi there,
