Igor Fedorenko closed MNG-3543.
-------------------------------
Resolution: Fixed
Fix Version/s: (was: 3.x)
3.0
I do not see this problem in the recent 3.0 snapshots. There are also automated
performance regression running here
https://grid.sonatype.org/maven-perf-ci/job/maven-performance-tests/ , so I
think all is good or at least under control now.

> Invoking readProjectWithDependencies for all modules takes very long time for
> some projects. For example, for servicemix-3.2.1 it takes about ~300 seconds
> in online mode and ~90 seconds. I ran the code under profiler, and it seems
> that in online mode this project is hit by MNG-3531. Both in online and
> offline mode, however, significant time is spent in
> DefaultBuildExtensionScanner.scanInternal(File, MavenExecutionRequest, List,
> List, boolean), so I wonder if there is a way to cache extensions somehow.
