Arnaud Heritier closed MAVEN-1786.
----------------------------------
Resolution: Fixed
Fix Version/s: 1.1-rc1
It's working fine. Your algorithm is better and allow us to not create a new
instance each time in the loop.
> Performance Optimization of the Reactor
> ---------------------------------------
>
> Key: MAVEN-1786
> URL: http://jira.codehaus.org/browse/MAVEN-1786
> Project: Maven
> Issue Type: Improvement
> Affects Versions: 1.1-beta-2
> Environment: OS windows xp, JVM sun 1.4.2
> Reporter: Emmanuel Renaud
> Assigned To: Arnaud Heritier
> Fix For: 1.1-rc1
>
> Attachments: Goal.java, reactor-jprofiler.GIF

>
> The Goal.checkForCycle method is a hotspot as the reactor starts.
> Most of the time is spent in creating HashSets and filling them (see attached
> screen shot).
> Instead of creating a new HasSet each time, reusing the same improves the
> performance of dependency analysis (see attached file Goal.java).
> Due to security policy in my company I can't checkout the sources and run
> non-regression tests, at least it works fine on our project.
