Thanks for the feedback. I am the Engineering Manager for Cloud Block Storage and I'd love to get a few details of the tests you ran.

What region were you running the tests in and when did you conduct your testing? We very recently made some networking changes that should have dramatically improved the cloud block storage IOPS capabilities.

Thanks for your time and don't hesitate to reach out if you have any questions, comments or concerns.

Thanks!

It was IAD, because that's the only place these instances are available. Darn convenient BTW, because I happen to be in DC right now. :)

Cool. Thought it was IAD, but wanted to verify we were talking about the same thing. We didn't officially launch the new flavors until 11/4 (even though they were out there before that) and we addressed some networking limitations just prior to launch. Thus, if you initially ran your tests with Cloud Block Storage prior to the changes, you very likely would have gotten the results you experienced.

In the performance tests we've run since the networking changes, we've seen substantially better IOPS performance with Cloud Block Storage. If you happen to rerun your tests we'd love to hear about the results!

Thanks for checking our products out.
