Your server is CPU bound (at least according to top). You should see some slight improvement with Memcached. IO is sitting at 0.0% but I have a feeling top is misreporting IO unless you have extremely fast disks or no IO at all (latter is unlikely considering MySQL processing is through the roof and the fact this is a forum).
If you're on InnoDB, increase the memory pool since you have plenty of free RAM. That will help too.
I was using DSO with xcache and after that high load i change to fcgi handler without xcache and it seems a bit better.
Is this possible?
I thought DSO was slow and i start using the fcgi....
What do you recommend me for caching (i don't mean for the php) as on Invision forum if i can use only one of them Apc, eaccelerator, memcache , xcache and so on as i must add a config line on the global.php file so the forum will know which one to use and is not possible to use two of them at the same time
I have already there (not loaded on php.ini) the xcache as when i use fcgi i must set (and i don't know how) the :
or it will show wrong stats on my forum as it did before....
When i use DSO on peak time i get a lot of /usr/local/apache/bin/httpd -k start -DSSL and the problem starts.
When i use Fcgi i get a lot of /usr/bin/php and the problem starts.
Thanks for your help
