Hi, I have an application using three different 0mq socket types: - PULL, to receive protocol buffer messages from outside for further processing, - PUB, to publish results (in protocol buffer format as well) - REPLY, to occasionally answer on status query, etc
All sockets are being polled in single cycle. It's a Scala application, using scala zeromq binding, and 2.1.11 0mq library. What I observe, being idle this app still utilizes more than 100-120% CPU on 4-cores linux box (using top utility). Under "idle" I mean that it is started and polling sockets, but notching is there to pull/publish. I played with setting timeout (using setTimeout on poller), latest I've set was to 2000000 microseconds, with no obvious effect on CPU usage. I know that most of the time it spends polling, since I monitor it with profiler. Is it normal, such a high CPU utilization? Is there anything wrong with what I'm doing? Something I should check/set ? Thanks for any help Sergey
