Carl Mercier from Defensio writes that Amazon EC2 performance pales in comparison to dedicated servers, even those with dated processors.
In a nutshell, my dedicated server is 10 times faster than an m1.small instance. TEN TIMES!!! For the same price! IO is also about 5 times faster than EC2′s local storage. And as a bonus, I get 4GB of Ram instead of just 1.7GB. After such a surprise, I decided to benchmark more expensive EC2 instance types to see how well my new best friend fares against my olf virtual friends. The results were equally surprising: my dedicated box is faster than a m1.large ($250/mo), faster than a m1.xlarge ($500/mo) and roughly as fast as a High CPU c1.xlarge ($500/mo).
