IBM MVS had an interesting alternative approach, which I believe was part of the scheduler: You could place an upper limit on the CPU allocated to a process. From a user perspective, an application would respond in (say) 2 seconds whether the system was completely idle or at normal load. This stopped users complaining that the system was slow as the system got loaded. In the case of jailed systems, it could also prevent (or minimize) traffic analysis of the system by a jailed process. -- Peter Jeremy _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
