Hi, I am using ZeroMQ in a project on Linux PREEMPT_RT. I have 2 modules A and B exchanging messages using PUB/SUB sockets. A sends a message to B, B receives it, then B sends back another message to A.
The test is to measure with an oscilloscope the latency between module A sending a message to module B and module A receiving the message sent by B. I did 2 kind of tests, one without using Hackbench, and one using Hackbench. The first test, I executed my 2 modules, and got a "stable" latency (between 14ms and 16ms). The second test, I executed my 2 modules, and also Hackbench with this command: hackbench -s 512 -l 600 -g 15 -f 25 -P Now, several times, I got some "peaks" at 25ms, 50ms... Have you any ideas of why I get theses results with hackbench? _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
