Those settings work for my laptop, too.  HotSpot (alone) builds in  
under 30 minutes.  I run JVM builds on my MacBook Pro 2.2Ghz, 4Gb,  
HOTSPOT_BUILD_JOBS=3.  Putting the build directory in /tmp (RAM disk)  
makes a huge difference.  The sources are reached over NFS (guest/host  
connection).  The hotspot build only takes about 20 minutes.  I'm  
looking forward to BSD-based builds, but for now am using Solaris/ 
VMWare.
