    I'm the author of the post and tech lead for K2. Happy to answer any questions!

      I'm doing some testing, and while my writes are <1s, I'm seeing E2E delivery latency of p95=2.5s / p99=7.5s. Is this roughly expected?

        The tail latency is higher than we would expect, but tbh our Consume API have work to do in terms of perf optimization. If it's not much to ask, can you share what's the max_records and the size of the stream that it was tested on? We are working on improving the read latency and you should be able to observe them in a week or so :)
