[jira] [Updated] (MNG-6632)
ArtifactHandlerManager.getArtifactHandler is inefficient
[ https://issues.apache.org/jira/browse/MNG-6632?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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]
