It wouldn't be benchmarking without some definition of Throughput... Full Disclosure: I have seen an earlier K8s benchmarking study, it could be related work. Among those of us who discussed the findings, one "knock" was that they only tested with TCP streams. Benchmarking for RFC 2544 Throughput requires UDP streams, no TCP flow-control complexities...

It wouldn't be benchmarking without some definition of Throughput... Nope. Not mentioned once. I shoulda hung an amount on that bet. Also, I was overly vague, I'd meant latency or latency under load... I have no idea why the k8 crowd thinks the network stack isn't something to worry about... > > Full Disclosure: I have seen an earlier K8s benchmarking study, it could be related work.
