AnilKumar Attuluri commented on FELIX-5665: ------------------------------------------- [~karlpauls] Yes, I moved it to the top and it didn't make a difference. > High CPU usage on > org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation > --------------------------------------------------------------------------------------------- > > Key: FELIX-5665 > URL: https://issues.apache.org/jira/browse/FELIX-5665 > Project: Felix > Issue Type: Bug > Affects Versions: framework-5.6.4 > Reporter: AnilKumar Attuluri > Attachments: IMG_1.jpg, IMG_2.jpg > > > We have been running some performance tests to prepare our OSGi bundle > (*running in Apache Karaf*) for production. > Just to give some background about our OSGi bundle, we converted an existing > Spring application into an OSGi bundle with all the current dependencies > packaged into the bundle as an uber artifact. > When we run >= 500 TPS (each of these calls results in a http call made via a > library) we run into this high CPU usage spikes reaching up to 100% CPU. > Please see the image attached, the spikes in the image are 100% CPU usage > while the average is about 40%. Also see the CPU sampler image which points > to > *org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation* > Is there an existing bug/documentation that already captures this? > We don't see this behavior when we run the same app in standalone JVM. > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
