Quite interesting results…

I’ll appreciate if you reveal you storage architecture: what is hw and os level configuration?

Secondly, I am really curious where you hit a limit. For instance looking on your 2.b test. It claims 3992 TPS that corresponds about 62.4 per CPU core. An average latency 3.43ms tell me that your CPU is under utilized (you have not included a metrics of HW demand during tests) but I can estimate CPU utilization was about 20 – 25%. You should be able to push your system up to 240 – 260 TPS per CPU core unless the cluster is bound to other resources. The logical question is what was abound factor during your test and what was disk, nic utilization?
