------------------------------------------
cstamas commented on PR #536:
URL: https://github.com/apache/maven-resolver/pull/536#issuecomment-2226999018
This PR causes noticeable slow down: building Quarkus (mvn clean install
-Dquickly) went from 9:20 to 11:10.
Ideas:
* make interning of dependencies configurable, default NO
* make interning of dependencyManagement configurable, default YES
* maybe intern only over some size limit?
The most offender is huge count of depMgt inherited from parent POM, so this
above would make sensible defaults.

> In DataPool, following can be done to reduce memory usage:
> * ArtifactDescriptor key does not have to be Artifact instance, is really
> just GACEV needed (is identity)
> * ArtifactDescriptors could have "interned" the List<Dependency> fields as
> well
