You shouldn't trust this reply
I have been on VPS for years and it was soooo bad, with so many daily websites down alerts that i was about to leave Dreamhost...
... until they made a nice offer for dedicated, and since no more alerts and everything is soooo much faster !
So i wonder why dreamhost advise VPS that are nothing worth compared to dedicated ?
Trust me, if you are serious about business don't use VPS but directly jump to dedicated !
(I would have loved that someone tell me...)
