Hi! I am trying to use zmq for sending video frames. The bandwidth I am using is 4Gbps up + 4Gbps down. I am using push/pull sockets (2 pair - one for each direction). So far, it is "working", but I need to lower the latency. - I have a 10Gbps link and cannot saturate it.
I tried to enable more io threads in hope it will increase the throughput and so reduce my latency... However, for reason I don't understand yet, the messages come unordered and/or seems broken. So I might have misunderstood something! * I have 1 context (but I have tried with 2 without any impact) * I create 2 socket in their respective thread(send / receive) - they don't know each other * I set 2 io threads * If I call "connect" 1x per socket -> I cannot send @ 10gbps ( I get about 10gbps total (up & down)). Which seems in line with the doc "~1GBps / working thread" * If I call connect 2x per socket, then the messages seems to be broken on receiver side I understand zmq is optimize for small messages/high volume, so that's why I seek to understand if it possible to tune zmq for such a use case large message (10MB) that use all the bandwidth available (10gbps) to reduce latency? Maybe it is possible an I am doing something wrong.. Can somebody help me with that? Thanks for you help Francis
