Just a side note. After some benchmarking, I recently discovered that c3.2xlarge does not actually have 8 cores, rather it had 4 real cores = 8 hyper threaded cores. I was very surprised by this and suspect most other AWS users would also be surprised. This is not to say that AWS is a bad deal, but I think Amazon could be a little more transparent about it.
