[jboss-osgi-issues] [JBoss JIRA] Commented: (JBOSGI-400) Provide stress test bundles suitable for profiling the framework

[David Bosschaert (JIRA)]

    [ https://jira.jboss.org/browse/JBOSGI-400?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12555479#action_12555479 ] 

David Bosschaert commented on JBOSGI-400:
-----------------------------------------

I'm sorry I thought I mentioned this in the commit mail, but the test does print this out as information during run. The default population is tiny (25). You can get a larger population (e.g. 10000) by setting the system property org.jboss.osgi.test.performance.service.size=10000 on the VM.

The system test is technically a subset of the bundle test so that's why I started it first. I'll look into the bundle test next.

> I recently connected the YourKit profiler to surefire while running the jbosgi performance tests. Unfortunately it seems that I'm profiling Arquillian and the JUnit overhead more than the framework itself.
> Would it be possible to also provide "framework-stress-test" bundles that we can drop into the standalone Runtime (or AS7) which would exercise framework in a similar way to what the performance tests do already. Perhaps each stress test bundle could start a Thread, which tests bundle/service lifecycle on a ton of bundles/services
> The profiler should not have to see significant overhead coming from test infrastructure.
