In a recent post, we benchmarked ‘r3’ instances using CoreMark. We also did disk bandwidth benchmarking on other AWS instance families: ('i' instance family, ‘c3’ instance family, and 'm' instance family). Today, we are sharing the same benchmarking ... Read More

Today, we explore the performance of wikibench on ‘c3’ instances. The methodology we used is similar to the one we utilized on ‘m3’ instances in this post here. In testing ‘c3’ instances, we used a paravirtual image for all our experiments. We used Ubuntu 12.04 LTS (64-bit architecture) for ... Read More

We thought that comparing CoreMark and FIO benchmark results for different instance families would be interesting. Essentially, it gives a good idea, and may help you decide, on which instance type you should use. To start, the numbers shown below are from benchmarking experiments which are explained ...
