改善ActiveMQ的写入性能

Question

The code at https://github.com/maxant/share/blob/master/DBJMSPerf/src/JMSWriter.java writes BytesMessages to a local ActiveMQ server.

I only manage about 200 messages a second (< 5 milliseconds per message).

Using the code at https://github.com/maxant/share/blob/master/DBJMSPerf/src/DBWriter.java which follows a very similar pattern, I am able to write more than 500 messages a second to a database.

In both cases, I handle transactions myself, because I want to simulate committing after each message and I re-use the connection since I want to simulate connection pooling.

I use the persistent delivery mode in the JMS example because I am trying to analyse a design which has high availability - messages may not be lost.

At http://activemq.apache.org/performance.html they cite writing messages ten times faster than I am able to.

How can I improve the performance of the ActiveMQ server?

You need to use a connection pool to speedup performance as you re-create all the JMS resources per message you send, and that is slow.

The JMS based connection pools has very often built-in pooling of session/consumer/producers as well and hence you can keep the code as is.

Apache ActiveMQ has a pool you can use, and there is also one from the Spring Framework.
