question, not an issue: What is the cost of open/close an unistream

[szguoxz]

I am trying to build a tunnel. I open a unistream, send the packet, and close the stream, then wait for the next packet. Is this too abusive? or should I open a stream, keep it alive, sending all the packets? will it be faster?

Streams are very cheap. Depending on what exactly you're tunneling, you might also want to consider using datagrams. Sending multiple packets in a row on a single stream will expose them to head-of-line blocking, which may or may not be a problem for you depending on what you're tunneling.

Hi, @Ralith, By using datagrams, does it mean I have to handle packet reordering and packet retransmitting myself like using UDP?

Yes.

Closing as the question appears to have been answered.
