Description

I'm currently optimizing a very large (2000+ submodule) project. ArtifactHandlerManager.getArtifactHandler is one of the CPU/memory hotspots, because for every `get` call it goes through the Map injected by Plexus. This Map has O( n ) lookup performance, because it is backed by an `Iterable`. It would be much faster to remember the artifact handlers that have already been found.
