[jira] Created: (ARIES-457) Efficiency problem in the method
listBundles() of class org.apache.aries.jmx.framework.BundleState
Efficiency problem in the method listBundles() of class org.apache.aries.jmx.framework.BundleState
--------------------------------------------------------------------------------------------------
Key: ARIES-457
URL: https://issues.apache.org/jira/browse/ARIES-457
Project: Aries
Issue Type: Improvement
Components: JMX
Affects Versions: 0.3
Environment: OSGi framwork: Felix
JDK: IBM JDK 6
Reporter: Wang Guang Zhe
Fix For: 0.3
In our environment, there are always 200 to 300 bundles in the OSGi framwork. When invoking listBundles() of the class BundleState, it spends more than twenty seconds which is too long to endure.

-----------------------------------------
Committed simple performance fix in revision #1029176. On my test system that brings the listBundle() down to a bearable < 5 sec with just over 400 bundles.

-----------------------------------------
Judging from circumstantial evidence this appears to be entirely down to FrameworkUtils.getBundleDependencies, which is called once for each bundle and then iterates over all the bundles to get their exported packages.
I tried this on Equinox and Sun JDK 6. So the problem is not related to the environment at all, although the bottleneck could be different on Felix ...
