I know this is a really general question that has many variables that will affect the answer, but I am hoping to get a feel for how heavily you all are loading your cPanel boxes.
I have one that is a dual-core 3gig processor with 2 gigs of ram and an obscene amount of disk space that is seeing some load issues with 50 some domains on the box. Is this a "Doh!" ?
How many domains do you put on a well utilized box before you call it full?
