The blog post mentions "P99 of ~1s of producer-to-consumer latency". What about just producer latency i.e. message successfully received into the queue ready to be picked up? S3 writes seem be in the low 100s of ms so I assume that's part of the quoted end-to-end latency.

Yeah our P99 for producer latency is ~400ms right now.

Sounds like you're currently optimized for throughput, not latency. (I work with customers for whom 10ms of latency for a 128kB write is too high.) What are your plans to improve latency?

None currently, if you need latency that low WarpStream is not a good fit and you should probably stick with something more traditional like a very well tuned Kafka cluster.
