[roded]

Hi,
Very nice project. Thanks for open sourcing it.
Please consider adding S3 upload benchmarks as well.

@dvassallo this is in-fact, a very interesting project and you have collected some great data. +1 to the request by @roded it would be very helpful if you can share the raw data for S3 upload testing that you might have done?

Also is the s3-benchmarking executable is capable enough to run both upload/download testing? ( sorry y I haven't tried it yet so asking a dummy question)
