Does your application have a tunable for in flight messages? If so, you may improve things by increasing that parameter.

What is the high-watermark and tcp buffer size configurations?On Wed, Feb 12, 2020, 23:18 Sylvain Fabre - INPIXAL <[email protected]> wrote:
Sorry, i forgot to add some missing information : When using a RTSP streaming, in TCP, in the same condition (ie 2Mb/sec stream) it is working fine. The kernel has already all the necessary options (TCP window size, etc, etc). So what i can conclude tigh now on the satellite network : A "regular" TCP connection is working A ZMQ PUSH-PULL connection is not working So the issue seems to be related to ZMQ, in a way or another. _______________________________________________ zeromq-dev mailing list [email protected] https://lists.zeromq.org/mailman/listinfo/zeromq-dev
