If you look at those benchmarks, for the same db queries on the same db backend, throughput and latency can differ by an order of magnitude. We're talking the difference between 200 or 2000 requests per second, or 50ms vs 500ms latency. That's not a rounding error.

My (and others') point is this obvious thumbs rule: If you hit the disk, that I/O will dominate the latencies. Even while using a scripting language.

E.g. a DB that fits in RAM is different, of course. It is hence easy to create benchmarks that generates every possible result.

So is your comment relevant to my point? Is there something about that benchmark which contradict the previous thumbs rule?

(And yes... With lots of calculations, scripting languages aren't a good idea either in many cases. Also obvious.)
