The stream already does that for you. >> Is it correct approach? I found two issues with this: > Well, I don't think haveing some data queued is a bad thing. Just set on some low and high watermaks: when more than "high" bytes are pending, stop writing, when less than "low" bytes are pending, resume. >> 1. I just written 10 bytes to client.

The libuv styream's write_queue_size keeps the value until the callback is called, even if data was sent a bit earlier, this is so that you can use it in the way I described above. >> 2. How much maximum value shall I allow to be hold by >> .queued_bytes ? Is there any guideline for optimal performance ? > I don't think there is a silver-bullet-value. If you put the mechanisms inplace you can then do your own benchmarks. You could also look into what values Node uses, as a reference.
