Turning off the precompiled headers is somewhat broken. It triggers a
single threaded build even when HOTSPOT_BUILD_JOBS has been set. With
this fix the compile times went from around 14 minutes to 2.5 minutes,
on an 8 core machine.
This affects both Linux and BSD builds, but has only been tested on
Linux. It would be great if someone with access to a BSD machine could
verify this fix.
