[Plugin: W3 Total Cache] 908 requests to load a single page

I am having some issues with my site and come to this after my server went down 4 times.

Looking at the processes running on my server, Apache (httpd) is getting hit pretty heavily, with some processes running up a very high amount of CPU usage to load my WordPress site. Doing some research to determine what plugins are being hit the most to load a single page I get this:

-bash-3.2# strace php index.php 2>&1 | perl -ne ‘if (/plugins\/([\w\d-_]*)/ ) { print “$1\n” }’ | sort | uniq -c | sort -n

908 w3-total-cache

W3-total-cache has a vastly higher number of requests than any other plugin to load a single page (908 requests). That, along with an average of only 6 HTTP connections to the server and the Apache processes continually pointing to a cache folder for the site.

So maybe something is wrong with my W3 Total Cache 0.9.2.4 configuration and I want to get sure about that. Or maybe thats how its supposed to work.

Can anyone help and give an advice ?

Thanks.
