Inefficient use of OperationContext.readResourceFromRoot

The single param OperationContext.readResourceFromRoot(...) variant can be quite expensive, as can be the 2 param variant if the 'recursive' param is true. The op returns a clone of the management model, and creating the clone can be expensive if the cloning is recursive and the affected tree is large.

There are a lot of calls like this in full WildFly that look like they could use the 2 param variant with recursive = false. Some of these are cloning the entire resource tree.
