Cool! Thanks for the research and experiment, and for following up on HN. I appreciated the attention to detail that was paid to documenting and explaining the consistency models. Be careful about running experiments from "t"-class instance types. Due to their ability to "burst" and consume extra CPU, the amount of system resources available to them is not consistent. This poses an experiment design challenge of ensuring that available system resources do not vary. It may be easier to run reliable experiments from another type. > Traditional Amazon EC2 instance types provide fixed performance, while T2 instances provide a baseline level of CPU performance with the ability to burst above that baseline level. They are intended for workloads that don't use the full CPU often or consistently, but occasionally need to burst. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/t2-instances.html http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/t2-instan... I am not sure if this will have meaningfully affected the accuracy of the results (probably not), but I thought I'd point it out for future reference.
