Comment (by stippi):
It definitely improved things quite a bit (second and third runs):
{{{
real 1m5.878s
user 2m25.134s
sys 0m41.105s
real 1m5.652s
user 2m25.156s
sys 0m40.971s
}}}
The effect is that load is spread across all cores much more consistently.
However, there are some curious effects still to be observed. When the
compile test begins, after jam collected targets, load jumps to between
80% and 90% on all cores, but slowly decreases over the duration of the
test. It could be dependent on what exactly is compiling, as there is a
short dip of load at a consistent time during the compile. I am attaching
a screenshot of the Activity Monitor graphs.
