Stefan Oehme updated MNG-6632:
------------------------------
    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.

See [https://github.com/apache/maven/pull/242]
