There are too many components involved when running the Linux
benchmark of running a build to know the scheduler is at fault. However
the slowdown did still exist when I minimized the window. I've at least
found that the FreeBSD schedulers can scale much better than Linux: you
can have a load of 100 or more before the system becomes unusable
whereas people are amazed to see loads of more than 15 on Linux.
