> I've been doing some test with cpu-intensive scheduling in FreeBSD > 2.2-stable, when I found what seems to be an error in the scheduler. Standard UNIX priorities work like this: prio 20 19 18 17 ... ^ ^ ^ ^ IF something here run it ---------------' | | | ELSE IF something here run it ------------------' | | ELSE IF something here run it --------------------------' | ELSE IF something here run it ----------------------------------' ... Note: these are base priorities, which the system will adjust based on I/O vs. CPU utilization. Your processes must have both been I/O bound. FreeBSD is doing what it's supposed to.
