> Key: AMQ-5876
> URL: https://issues.apache.org/jira/browse/AMQ-5876
> Project: ActiveMQ
> Issue Type: Improvement
> Components: jaas, security
> Affects Versions: 5.11.1
> Reporter: Gary Tully
> Assignee: Gary Tully
> Labels: jaas
> Fix For: 5.12.0
>
>
> With a large number of entries ( 200,000 ) in the "org.apache.activemq.jaas.textfiledn.user" file the performance seemed to degrade.
> To demonstrate the performance difference;
> {code}
> 1) for 100 entries and calling initialize,login(),commit 10 times - Time taken is 73 miliseconds
> 2) for 200,000 entries and calling initialize,login(),commit 10 times - Time taken is 5020 miliseconds
> {code}
> Suggested improvements:
> - avoid loading the org.apache.activemq.jaas.textfiledn.user file each time - in PropertiesLoginModule.java, the file is only read when it changes, using the file modification time.
> - avoid iterating through the Properties object, using a Map instead to retrieve the userName
