             Summary: Dependency convergence rule is very slow in larger projects
                 Key: MENFORCER-271
                 URL: https://issues.apache.org/jira/browse/MENFORCER-271
             Project: Maven Enforcer Plugin
          Issue Type: Bug
          Components: Standard Rules
    Affects Versions: 1.4.1
         Environment: Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)

I noticed that DependencyConvergence can take up to 10 seconds or even more in modules with almost 300 direct and transitive dependencies (reported by {{dependency:tree}}).
These modules are part of a JEE project based on JBoss EAP 6.4 which imports a couple of EAP BOMs. Unfortunately I am not allowed to share this project.

I profiled the rule via VisualVM and these are the top 5 hotspots:
!visualvm.PNG!

The number of {{parseVersion}} calls seems excessive.

See attached {{visualvm_settings.xml}} for reference.
