Hello vemv, we have time complexities in every stream command, and the reason there is no latency documentation is because it follows the Redis normal latency, that is, like blocking lists or Pub/Sub work: as soon as something is available for consumers waiting, it is immediately sent to the socket of such consumers. So you can expect extremely low latencies without any differences compared to other Redis commands. However I'll try to reply to your question in more details in that issue. Btw what is bad is that you did not find your answers in the Streams intro doc. I'll update that too.
