I've been running some benchmarks on a number of popular virtual and cloud service providers, to see what you really get for your money.

All tests are being run on an empty unused server, I have run each test more than once but have generally seen little variation so have only posted the best result for each instance tested.

The final test is taken from a local VM running on my MacBook Pro, just to put things in perspective.
