> Key: MNG-6632
> URL: https://issues.apache.org/jira/browse/MNG-6632
> Project: Maven
> Issue Type: Bug
> Components: core
> Affects Versions: 3.6.0
> Reporter: Stefan Oehme
> Assignee: Herve Boutemy
> Priority: Major
> Fix For: 3.6.2
>
>
> 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.
