I use perf/remote_thr.cpp with this change:

diff --git a/perf/remote_thr.cpp b/perf/remote_thr.cpp
index 3295f2e..a8fe4da 100644
--- a/perf/remote_thr.cpp
+++ b/perf/remote_thr.cpp
@@ -55,6 +55,14 @@ int main (int argc, char *argv [])

     }

+    int64_t j = 8000;
+
+    rc = zmq_setsockopt (s, ZMQ_RATE, &j, sizeof(j));
+    if (rc != 0) {
+        printf ("error in zmq_setsockopt: %s\n", zmq_strerror (errno));

+    }
+
     //  Add your socket options here.
     //  For example ZMQ_RATE, ZMQ_RECOVERY_IVL and ZMQ_MCAST_LOOP for PGM.

and execute it like this:

./remote_thr epgm://eth1\;231.192.0.1:9999 255 10000
