Hi Steven
I tried numbers like 10,000 and even then it took almost 7 seconds.
It seems the throughput is the bottleneck here.... Thoughts? Do I need PGM tweeking?
Transport: ZMQ
Protocol: epgm
Messages recd: 10000
Total Time: 7930204 us
Throughput: 0.15132 Mbps
Avg per msg: 793.02 us
Ours is a gigabit network so 160us to 200us round trip for individual messages looks ok right?

That's a really small amount of messages to test a transport that can handle 100,000+ per second.
Average / message: 168.421 us
Max time: 200 us

One-way latency for datagrams is 80-90µs with most gigabit networks, you need 10 GigE or InfiniBand for lower latencies.
