Re: [jgroups-dev] jgroup cluster - throughput is not increased

i want to measure the number of messages processed by the each java instance.

Scenario
i have a batch job when running in a standalone jvm , is able to process 220
messsages per second. absolutely there is no bottle neck either in
application layer or oracle database layer. i profilled and verifed the
thread dumps for the run.

i want to increase the throughput further, then i created a jgroups cluster
with two nodes.
But to my surprise the throughput is still only at 240 per second, i
expected a big jump in throughput because now the batch is running with 2
nodes and there are no synchronization issues.

the configuration i used in both the nodes is as follows.

-Djava.net.preferIPv4Stack=true
-Djgroups.start_port=8100
-Djgroups.bind_addr=172.19.112.232
-Djgroups.tcpping.initial_hosts=172.19.112.232[8100],172.19.112.234[8101]

i am using the default tcp.xml for the configuration, similarly i tested
with 2.12 but the performance is not improved.
even i changed the property enable_bundling from true to false because i a
using old jar, but there is no fruitful results.
