I wouldn't recommend doing benchmarking on a virtual server.
You have no idea how busy the real server is, (noisy neighbors, etc), so it's impossible to have comparable results from benchmark to benchmark.
FWIW, If you use one of the largest instance types (4x large or whatever), the VM will probably be on it's own host which would mean you're unlikely to have neighbors ;)
When benchmarking, it's best to remove assumptions based on "probably" though right?
It's cloud.
You still have to deal with the storage fabric.
