Hi, hardware: * Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz * 16 GB RAM * HDD ST500DM002-1BD142
timings: Currently Java Broker 6.1.1 seems to behave as version 7.0.0 RC. 10 - 30 messages per second. Interesting is when I increase message size to 10kB. Messages per second are same but throughput is increased ten times. When I use nonpersistent messages everything goes smooth. Thousand of 1kB messages are sent within 1 second. There are no extra JVM options, just the ones which are present in bin/qpid-server file. Heap and direct memory on broker is also default - -Xmx512m -XX:MaxDirectMemorySize=1536m. I tried to increase to four times larger ones -Xmx2048m -XX:MaxDirectMemorySize=6000m, but there was no change in messages per second. Unfortunately vmstat gives same values pro CPU, I am sending at least top output. 6.1.1: %Cpu(s): 6.9 us, 0.3 sy, 0.0 ni, 68.5 id, 24.1 wa, 0.0 hi, 0.2 si, 0.0 st 7.0.0: %Cpu(s): 2.4 us, 0.4 sy, 0.0 ni, 71.2 id, 25.9 wa, 0.0 hi, 0.0 si, 0.0 st When we tried on server where message store was stored on SAN disk, sending of messages increased to 500 msg/sec. With C++ broker on same machine we are able to send 5000 msg/sec. ps. I cannot create queue in 7.0.0 version by webgui when queue contains '.' character, in 6.1.1 version queue with dot in name can be created by webgui Keith Wall wrote > Hi Tomas, > > Nor can I reproduce any discernible difference in performance between > 6.1.1 and the 7.0.0 RC with your Java code.
