Imaging slow network.
If producer sends data faster than they can be sent through ... it is clear, right? ;)
If HWM is set at receiver side situation is a sort of simular with slow link case.

my reading of teh manual pages is that HWM has no effect on sending a message(only if hwm is set for teh receivers).on the other hand, when i set it in an experiment, it seemed to have an effect.on the other other hand, i normally and doing fan-in fan-out on both sidesof my push/pull links, so an hwm on the sending side is problematic.On May 16, 2011, at 7:22 AM, Ilja Golshtein wrote:just to verify, to set hwm limits on a push pull, i set it just on the pull end,after the zmq_socket call and before the zmq_connect call. correct?Sometimes yes, but generally not .If sender is faster than receiver (otherwise everything is fine) queue would grow up at sender side if it is limited at receiver side.Assuming the goal is to block, you need HWM at both sides.[As far as I understand - hope guru correct me if I am wrong]--_______________________________________________
