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. -- Bruce Cran
