This part I'm skeptical: "Compared to CPU time, CPU instruction is a better metric, as it reports the same numbers regardless of CPU models and CPU loads for the same request." CPU instructions will be more stable

It's really impressive that it can handle these many container placements. But, honest question, what's the value of determining how fast can we schedule a million containers? This question is not just for Nomad but other cluster

The explanations here gave a lot of details on the effect, but IMHO, not as many details in the cause of Coordinated Omission (CO). Most of what I'll be saying here comes from a CMU's paper titled "Open vs Closed: A Cautionar

Also for those who enjoyed this paper, I think you will also like CMU's Prof. Mor Harchol-Balter's book[1] on queuing theory applied for designing, and analyzing performance of, computer systems. Personally, I don't know of a

Check out Gatling[1], which is based on Scala, Akka, and Netty, and last time I checked works on Windows. The only thing missing would be an out-of-box solution for distributed load generation, which I believe is being developed. But today,

There's a branch from Gil Tene (Azul) that fixes wrk for the coordinated omission problem, which he explains in the readme of that same repo[1]. [1] https://github.com/giltene/wrk2

It seems to me that the workloads on Digital Ocean are not fully utilizing the block device. FIO shows about 50% util for DO, and 81% for Linode on the queue depth=1 test, and 70%/82%, respectively, on the queue depth=8 test. Which se
