I would like to get some help, since I sent Donncha an email through his website but got no response.
The point is that on my blog http://www.noticiasautomotivas.com.br (which has around 60.000 visitors per day), my load average is the same, with WP Super Cache activated or deactivated.
My server is an Intel i7 860, with 8 GB of RAM, and the load average is always around 8.00.
I talked to WiredTree support and they made all kinds of checks and improvements on the server, as regards Litespeed, PHP, MySQL and everything, but the load wont drop.
If the load is always the same, it feels that WP Super Cache is not necessary, and is not gonna help in anyway.
The pages are being cached, since if I enable it, within 60 minutes I get around 800 cached pages.
Any hints as about what should I do to solve this?
I know the plugins will be blamed for this. But until sometime ago, the load used to be 2.00, with exactly the same plugins....
