X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list Reply-To: zhangweiwu@realss.com List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 28 Feb 2004 03:37:52 -0000 Hello. I thought scheduling priority is the kind of absolute priority, that is only when the higher priority process don't ask for resource, can the lower priority process gets resource. If the higher priority process sucks, the lower priority process starvs. Now I have a old Pentium-mmx 166 box, running mpg321 fine. I wish to listen to music when recompile the kernel, so turn on the music, do: #nice make; I thought "nice make" use the resouce mpg321 left to it, but actually the music process is seriously disturbed, it begins to sound like .... terrible. So I don't realy understand the scheduling priority mechnism in FreeBSD? _________________________________________________________________ 与联机的朋友进行交流,请使用 MSN Messenger: http://messenger.msn.com/cn
