Are those performance measurements meant be impressive? Seems on par with something threwn around with Python in 5 minutes.

Please don't be a jerk or put down others' work on HN. That's not the kind of site we're trying to be.

You're welcome to make your substantive points thoughtfully, of course.

    Pointing out facts is not being a jerk. If you don't want feedback, don't solicit it.

    Also if you disapprove, modding down is enough, you don't need to start a meta-discussion thread, which is itself a discouraged practice.

      It depends on the context. For example, imagine telling a teenager that their face is covered in acne, or (to use an old example of pg's) telling an old person that they will die soon (> If you don't want feedback, don't solicit it.

      Totally fair, if this were “single-node HTTP handler on localhost”, then yeah, you can hit big numbers quickly in many stacks.

      The point of these numbers is the envelope: 3-node consensus (Raft), real network (not loopback), and sync-majority writes (ACK after 2/3 replicas) plus the crash/recovery semantics (SIGKILL → restart → offsets/data still there).

      If you have a quick Python setup that does majority-acked replication + fast crash recovery with similar measurements, I’d honestly love to compare apples-to-apples happy to share exact scripts/config and run the same test conditions.

        Good NICs get data out in a microsecond or two. That's still off by quite the order of magnitude, but that could be up to the network topology in question.

          Durable consensus means this is waiting for confirmed write to disk on a majority of nodes, it will always be much slower than the time it takes a NIC to put bits on the wire. That's the price of durability until someone figures out a more efficient way.
