I ran the build with an empty maven repository on the machine spec'ed above.
The results are:
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 94 minutes 7 seconds
[INFO] Finished at: Thu Jun 23 16:40:50 EDT 2011
[INFO] Final Memory: 626M/935M
[INFO] ------------------------------------------------------------------------

Much better!

I updated the wiki docs with this spec as the suggest minimal configuration of a
build machine, reflected the build times, and compared it with the 1GB build
machine configuration I tested and reported earlier.


Thanks for everyone help and tips!
The GMOxDEV build docs are all up to date now, and hopefully useful enough to
answer most questions about building G3.0.
