I never had results like you. I always noticed improvements between 2.0>2.2>3.0 I'll do some tests.
Where I have problems for now, it is on some OS. While with OSes like Suse,OpensSolaris,Windows 7 we have good perfs results for the build, on linux servers like ubuntu, fedora , ... we have results 4x slower. We are studying these problems and if we succeed to explain the issue we'll share it here (I suppose that many of us are using linux for continuous integration servers) Arnaud Héritier Software Factory Manager eXo platform - http://www.exoplatform.com --- http://www.aheritier.net On Tue, Apr 27, 2010 at 2:10 PM, Jörg Schaible <joerg.schai...@gmx.de>wrote: > Hi guys, > > it's not the first time I complain about Maven performance, but it seems M3 > is heading the right direction.
