I noticed that recently my website is experiencing slow page loads. I'm running on dedicated server I have < dozen websites on it. The biggest site (DF CMS) and it has over 9000 members. The other sites are non significant. I'm running CentOS, 2.4Ghz Celeron, 2GB RAM, Cpanel/WHM, PHP5 and mySQL 5.0.92.
What can I do to optimize my server settings to make the website faster?
You need to debug, then act accordingly to your findings.
What would be the best way of debugging? DF software has not changed on the server. Only server OS and CPanel upgrades are being done automatically. I'm simply looking for some server optimization help.
Man, this site loads VERY fast. You think that the Developers would have their settings posted here so others can optimize their Dragonfly websites properly. Maybe such guide exists but I just don't know about it? I'm pulling my hair out here. Any assistance would be greatly appreciated.
ssh into the server and type "top" (no quotes), by default process lists are ordered my cpu usage, have a look whats the process using more cpu
if is mysqld then: use phpmyadmin to delete duplicate keys
a bug in DF ... i think it was a phpnuke or an installer issue, supposed to be fixed in new DFs, but i guess an old bug in phpmyadmin shuffled things around confusing the water
nano said there is not "simply" here, well he does have a point and "change A to B" can't be easily done ... experienced debuggers with shell access may take few minutes to understand where the problem come from, and sometime to fix it
we going totally blind here I'll be surprised if we gonna be able to fix it
Server specs (Server OS / Apache / MySQL / PHP / DragonflyCMS):
I watched the TOP process run on the screen. CPU % increased when I saw 5 PHP processes being at the top of the list.
I also set my DF Security as per the attachment. When I had the Unkown User-Agents set to active my site users were receiving banned messages. "Unkown User-Agents"=Active increased the site performance but I had to deactivate it because the users were unable to access the site.
