For the new build you have to explicitly choose release,fastdebug or slowdebug.
(--with-debug-level=release,fastdebug or slowdebug)
So you do not need to turn off fastdebug, it defaults to release.
As for the demos and samples. They compile so much faster that there is no
point in turning them off. 10 seconds on my workstation, and during
they take no detectable time at all.
You probably want to do: --with-jvm-variants=server
when building on a 32bit machine since the default is client,server
(client,server,kernel on 32bit windows) And building extra libjvms does take
a significant amount of time.
