JMX inefficiently handles resource adapters ------------------------------------------- Key: WFLY-6250 URL: https://issues.jboss.org/browse/WFLY-6250 Project: WildFly Issue Type: Bug Components: JCA, JMX Affects Versions: 10.0.0.Final Reporter: Stefano Maestri Assignee: Stefano Maestri Attachments: README.txt, xaa, xab, xac, xad If you connect to JBoss over JMX when it has many rars deployed (over 500), long running high CPU is seen in the following calls: {code} at org.jboss.as.controller.ModelControllerImpl.execute(ModelControllerImpl.java:188) at org.jboss.as.jmx.model.ResourceAccessControlUtil.getResourceAccess(ResourceAccessControlUtil.java:85) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:51) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:61) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:61) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:61) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:61) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:61) at org.jboss.as.jmx.model.RootResourceIterator.doIterate(RootResourceIterator.java:61) at org.jboss.as.jmx.model.RootResourceIterator.iterate(RootResourceIterator.java:43) {code} It's evident that it is iterating over each deployment (each resource adapter counting as a deployment), but for each deployment, it is also iterating over all resource adapter's and their config properties. So it would iterate over all 500+ resource adapters once for each deployment, so it iterates over all 500 adapters at least 500 times. Is there anyway we could avoid that n^2 iteration for deployed rars?
