Thanks tamara, I guess I was confused because the thr tests have the reverse
start order.
I have had some success running the PGM from java on windows, although the
throughput for pgm is very low for both the c++ --> java and the out of the
box c++ to c++ tests I've run (around 9Mb/s). The java j_local_thr test
yields 108Mb/s using the same 2 machines.
Are there any particular tunables I should know about? Is this to be
expected on windows? I don't see any significant cpu/network usage.
Thanks!
Robin
Some output:
The PGM version
S:\Software\zmq-1.0.0\perf>pgm_remote_thr.exe wimp "192.168.0.200;
226.0.0.1:7500" 100 100000
iface to connect to local_exchange: 192.168.0.200;226.0.0.1:7500
message size: 100 [B]
message count: 100000
Your average throughput is 11830 [msg/s]
Your average throughput is 9 [Mb/s]
The other command line I'm using for the pgm_local_thr
C:\zmq-1.0.0\perf>pgm_local_thr wimp "192.168.0.195;226.0.0.1:7500" 100
100000
local_exchange network: zmq.pgm://192.168.0.195;226.0.0.1:7500
message size: 100 [B]
message count: 100000
Start pgm_remote_thr on remote host and pres enter to continue.
Pres enter when pgm_remote_thr exits.
The non PGM version in java is much faster
C:\zmq-1.0.0\perf>java -Djava.library.path=c:\zmq-1.0.0\java -classpath
c:\zmq-1.0.0\java;.\ j_local_thr localhost 192.168.0.195 100 100000
message size: 100 [B]
message count: 100000
Your average throughput is 136239[msg/s]
Your average throughput is 108[Mb/s]
