Bootstrap cloud shoot-out part II

A recent comment by Martyn on my cloud performance shoot-out post prompted me to do another round of testing. As the bootstrap process I described on the last post evolved, it’s always a good idea to test it anyway, so why not kill two birds with one stone? The comment suggested that the Amazon EC2 micro instance is CPU throttled, and that after a long period (in computer terms: about 20 seconds according to the comment), you could lose up to 99% of CPU power. Whereas on a small instance, this shouldn’t happen. So is EC2 small going to perform way-better than the micro instance? How is it going to perform against Linode or Rackspace equivalent VPS?

Webfaction fail. over.
