I am currently working on the cxf jms transport for cxf 3.0.0. As the
transport is change pretty heavily I am doing some performance tests to
see it is on par with cxf 2.x.
During my tests I have a very good overall performance for one way
messages without persistence. For most time periods I get about 16 000
msg/s. Every about 5 seconds though performance goes down to 100-1000 msg/s.
Does anyone have an idea what the reason is for this problem? Can I
avoid it? I would like to achieve more or less stable performance.
I first assumed this might be a garbage collection but using jconsole I
can not see garbage collections at exactly the problematic times.
The full performance test code is at:
https://github.com/cschneider/performance-tests/tree/master/cxf
The activemq.xml I used is also stored there.
To run the test do this:
- Starting an activemq 5.9.0 broker with the config from the checkout
- Run the com.example.customerservice.server.CustomerServiceServerJms
- Run the com.example.customerservice.client.CustomerServiceClientJms
The client will send 160 000 cxf soap messages for warmup and then the
same number again for the real test.
I am using these java options for the test code:
-server -Xms256m -Xmx4048m
My system has 16 GB of ram.
I would be happy about any ideas you have about it.
