Allo! This is our first attempt at using zeromq. We would like receive some feedback on what may be wrong with our setup and testing.
We conducted the performance test on two Windows XP Pro SP3 machines (multi-core, 2 GHz, 2 G RAM, etc) directly connected together through their 1 Gbps NIC. For the performance testing, we used the local_thr.c and remote_thr.c from the perf directory in release 2.0.6 zeromq source tree downloaded from the web site. The libzmq library and both .c files were successfully built using the MSVC 2008 Express and the MSVC project file found in the source tree. No changes were made to the project settings. Here is a short list of the test results (stdout) from the local_thr.exe: C:\Work\TestZeroMQ>local_thr.exe tcp://192.168.35.209:667 170 10 message size: 170 [B] message count: 10 mean throughput: 625000 [msg/s] mean throughput: 850.000 [Mb/s] C:\Work\TestZeroMQ>local_thr.exe tcp://192.168.35.209:667 170 100 message size: 170 [B] message count: 100 mean throughput: 309 [msg/s] mean throughput: 0.420 [Mb/s] C:\Work\TestZeroMQ>local_thr.exe tcp://192.168.35.209:667 170 1000 message size: 170 [B] message count: 1000 mean throughput: 201 [msg/s] mean throughput: 0.273 [Mb/s] C:\Work\TestZeroMQ>local_thr.exe tcp://192.168.35.209:667 170 2000 message size: 170 [B] message count: 2000 mean throughput: 201 [msg/s] mean throughput: 0.273 [Mb/s] C:\Work\TestZeroMQ>local_thr.exe tcp://192.168.35.209:667 1700 10 message size: 1700 [B] message count: 10 mean throughput: 24 [msg/s] mean throughput: 0.326 [Mb/s] C:\Work\TestZeroMQ>local_thr.exe tcp://192.168.35.209:667 1700 100 message size: 1700 [B] message count: 100 mean throughput: 21 [msg/s] mean throughput: 0.286 [Mb/s] These results are not in line with the expected performance results found on the zeromq web site. Is this a known issue? Are we make a newbie mistake somewhere? Are their Windows specific build instructions/settings/issues we should know?
