Are you using a PHP pre-compiler/cache? That can help. Also a compiled from source Apache, MySQL, PHP, etc instead of the canned binaries can help a lot.
Zend is installed... the rest is default fedora stuff

Have you studied your phpinfo(); page and verified optimum parameters? The defaults of the Fedora binaries might be less than ideal with your load. Important: if you're using PHP as CGI instead of module that will cripple the system with your load.
Not sure about that... I'm sending you a pm with a link to my php info page so you can help if you have the time...

Have you looked at what if anything is hogging the CPU, via a console "top" command or other detailed command?
Top command shows nothing special. At top is httpd of course... Is it possible to give me a list of any other commands?

With the servers on one box you likely don't want persistent connections but is something to play with. Using a socket connection instead of IP to localhost might be faster (can XOOPS use socket?).
i think peristent connections are not used... How can i check that?

What about external content like ads? Any local db queries before the external calls? Using phpAdsNew stand alone or with an XOOPS module?
phpadsnew is used standalone but it is running from a different machine. This machine only serves the domain we are talking about with no external scripts...

There is a little script floating around that will show the query times and counts. That might show if you have a very high query count or time or just a lot of users.
This is the one i found...

...i hope it's the one you 're talking about. I 'll give it a try...

Careful caching of course is a factor.
I'll check caching again... I'll come back with results...

You might hack the photo gallery for better performance. I'm not familiar with yours but things like random pics are usually pretty db intensive. No doubt your users are hitting the pics pretty heavy.
As i understand, this is not a db problem... MySQL load is low... System load is the one that goes high...

I'm not a fan of using any chat apps that anon users can get to even if you then force a login. They will frequently hit the link and load the app before seeing the login.
I tried turning chat off but there was no improvement at all. It actually got worse because all chatters returned to site browsing... :(
Thanks for your help... If you think of anything else, please post it here. I 'll come back with any results soon...
