Still not seeing the promised speed up when on a mac (and actually always a bit slower). But definitely seeing the improved times on a linux box (Linux 2.6.32-24-server #41-Ubuntu x86_64 GNU/Linux )
So it seems that if you are on a mac then be aware that upgrading to mvn 3 could at best give you the same build times as mvn 2 and at worst be a tad slower out of the box. If you run with -T options it seems to deliver on performance. The typical build times with mvn 2 are: Linux: Total time: 57 seconds (always < 1m) Mac: Total time: 1 minute 11 seconds (usually around this time +-5 seconds) Initial build times using Apache Maven 3.0-RC1 (r997478; 2010-09-15 14:57:55-0500) Linux: Total time: 1:53.554s Mac: Total time: 1:56.945s Subsequent build times: Linux: Total time: 48.646s Mac: Total time: 1:20.053s I'm only added the last run of 3 from each since the runs were all pretty close. This was tested on 2 different macs but only 1 linux box (which is a hefty box so the times are a bit unfair towards the linux box). Running with -T 1c brings the mac builds under a minute (2 cores on the macs). Mac: Total time: 58.675s (Wall Clock) And an astounding 1/2 time builds on the linux box (8 cores) Linux: Total time: 32.193s (Wall Clock) On Wed, Sep 15, 2010 at 3:34 PM, Benjamin Bentmann <benjamin.bentm...@udo.edu> wrote: > Hi, > > in preparation for the release of Apache Maven 3.0, the Maven team is > seeking your help to discover regressions since Maven 2.x.
