QUESTION: How to connect faster?
jvmusin opened this issue · 1 comments
Hi.
Not an issue actually, but a question. Is it normal that it takes about three seconds to connect my machine from one port to another? And how can I make it faster?
Sorry if this question has already been asked, I couldn't find it in issues.
I use this snippet
fun newAgent(port: Int): Agent {
val agent = Agent()
val stream = agent.createMediaStream("data")
agent.createComponent(stream, Transport.UDP, port, port, port + 100) // RTP
return agent
}
val agent1 = newAgent(8081)
val agent2 = newAgent(8082)
val sdp1 = SdpUtils.createSDPDescription(agent1)
val sdp2 = SdpUtils.createSDPDescription(agent2)
SdpUtils.parseSDP(agent1, sdp2)
SdpUtils.parseSDP(agent2, sdp1)
thread { agent1.startConnectivityEstablishment() }
thread { agent2.startConnectivityEstablishment() }
Thread.sleep(10_000)And it writes this to the console

In the very end of the logs you can see a pause between 8:20:19 and 8:20:22 where nothing happens and only after the last message we can use the established connection.
