[jboss-jira] [JBoss JIRA] (WFLY-5234) Use of ModelNode.asPropertyList() is slow when marshaling potentially large subsystem model chunks

Use of ModelNode.asPropertyList() is slow when marshaling potentially large subsystem model chunks -------------------------------------------------------------------------------------------------- Key: WFLY-5234 URL: https://issues.jboss.org/browse/WFLY-5234 Project: WildFly Issue Type: Bug Components: JCA, JMS, Security Affects Versions: 10.0.0.Beta2 Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 10.0.0.CR1 ModelNode.asPropertyList() results in a clone of the model node. If the node is very large this can be expensive. We use this call quite a bit in subsystem xml marshallers. The cost is not likely to be significant in most places, but in a few cases where users may end up adding a large number of nodes of a particular type, moving away from this call to another idiom that doesn't involve cloning may help with performance. I've heard of a user planning to add thousands of datasources, for example, and wanting very fast performance of the write ops to add those. Things I plan to look at: (xa-)datasources messaging destinations resource adapters JCA connectors security domains
