rqlite creator here. I have performed a fair amount of performance testing, some of which I outlined in a talk to the CMU Database Group a few years ago. Details:
An important thing to note: this testing was done 4+ years ago, on moderately-powerful hardware for the time. With higher-end, more modern hardware you may get even better results.
Thanks for the reply. Yeah, that’s the talk I was referring to.
I suppose I could try my own benchmark out tbf. I’m curious to see what it can do on today’s hardware. I would think it’s mostly network-bound for Raft consensus, though the 10x ping time increase you demonstrated without an appreciable drop in writes suggests it’s more complex than that.
I did introduce Queued Writes[1] since that talk, allowing you to trade off performance versus immediate durability. It may interest you -- network is much less of a factor then, and you should get a 10-100x increase in throughput.
