Mark Bowman commented on MDEP-230:
----------------------------------
I've been having a quick look into this by checking out the
maven-dependency-plugin source code and adding debug:-
http://svn.apache.org/repos/asf/maven/plugins/tags/maven-dependency-plugin-2.1
It appears to be slowing down in the extract method within the TarUnArchiver
class. This class is part of the plexus-archiver-1.0-alpha-9 package.
Checking this package out and inserting debug:-
http://svn.codehaus.org/plexus/plexus-components/tags/plexus-archiver-1.0-alpha-9
shows that the TarUnarchiver class is extracting individual files and taking
~50ms per file.
> Performance is really bad for large artifacts
