Hi guys,
Anybody knows if evapi sends messages to the clients immediately when async_relay is called?
The normal behavior is 1 or 2 netstrings per message but I see that sometimes it starts to enqueue and starts sending for example 4, 5, 15, 30, 52.....327, 645 per message.
Cheers,
Diego

I believe this is up to the TCP stack / OS rather than any aspect of Kamailio's implementation.
It's weird. When sends 1 or 2 net strings per message I see that my client receives ~18 messages per second. When starts to grow the amount of netstrings the messages received decrease to 1 per second and fewer.
Any advice?
Diego

Do you mean that the objective rate at which the client receives the messages decreases, or that a very large amount of them end up buffered into a smaller number of packets, with the same effective throughput?

Sorry, maybe this log clarifies what I meant:
These are the messages that my client read. It's connected to 127.0.0.1 to kamailio evapi.

Hello,
Can you check with netstat the recv and send queues for the sockets used in this communication? If the recv queu for receiving up is big, then it cannot handle the traffic fast enough.
Cheers, Daniel
