Scenario: I'm a freelance designer, I host my clients websites for a fee. I currently use Heart Internet Reseller for this which is shared hosting. I don't have SSL or any flexibility. This costs me £42 per month ($66) - I feel this is quite a lot for shared hosting.
I'd like to move to a VPS so I have more control and scalability for application such as Magento. I'd like it semi managed solution, for example Media Temple: http://mediatemple.net/webhosting/dv/, my current budget allows for their base package ($50 per month).
Would moving myself and about 30 clients over to this base package give me better or worse performance than my reseller plan at the moment? Media Temple did try explain how the performance is based on some CPU units, although I don't quite understand it.
