I have a dedicated web server with codero.com. Over the weekend it just slowed way down. Now the page loads take forever. I spoke to their tech department and they tell me my server is not running under a high load and I my server resources are not being maxed out. Is there a web administrator out there who would know how to investigate and see if they can figure out what is causing my site to slow down? Is there a way to just take a peek around and see if you spot some problems or errors? The issue is I have the Plesk control panel with 30 domain license so I am operating 3 major sites (all "LIVE") on this 1 server. Anyone peeking around inside needs to be very carful not to crash my sites or lose any data.
I have full root access and you can use Putty to SSH to server. The server type is a Celeron 1.7 GHz with the operating system Fedora 7. I run PHP and MySQL.
