Robert Hodges resolved HEDERA-34:
---------------------------------
Resolution: Fixed
This problem is solved by switching to the JGroups 2.4.x stack defined by the
total.xml configuration file. This uses a different total order algorithm
based on a sequencer. Speed seems to be about equal to Appia and the test
passes.
> Hedera performance test does not complete when sending more than a few
> messages with JGroups 2.4.1

> Key: HEDERA-34
> URL: https://forge.continuent.org/jira/browse/HEDERA-34
> Project: Hedera
> Type: Bug
> Environment: MacOS 10.4, behavior also replicated on Linux / CentOS 4.5
> The JGroups library version is JGroups 2.4.1-SP4
> Reporter: Robert Hodges
> Assignee: Robert Hodges
> Priority: Critical
> Fix For: Hedera 1.6.3
>
>
> The Hedera ChannelPerformanceTest does not complete if you run it using
> JGroups 2.4.1. Older versions such as 2.2.9 appear to work better.
> The problem seems to be that while messages are sent normally over the
> channel, not all messages are received. The test then hangs waiting for the
> missing messages to arrive. To set up this this test, edit run-test.sh to
> use JGroups, replacing the CONFIG line as follows. This specifies 2
> senders, 2 receivers, and 1000 messages of 1024 bytes each.
> CONFIG="1 2 2 1000 1024 /hedera_jgroups.properties"
> Run the test by starting run-test.sh in two windows, which should result in
> output similar to the following in each window:
> hartzpass:~/workspace_os/hedera rhodges$ ./run-test.sh

> actually received. In my test runs it seems that about 140 or so messages
> are received.
> If you run using Appia, which is the default for run-test.sh, the test
> completes without any problems. You can also make the test complete by
> setting the number of messages to a very small value, such as 10.
