I notice that when I run a process "niced", only the CPU priority seems to be effected. If the process starts heavily accessing the disk and gets a large number of disk I/O requests into the queue before a higher prio process runs, the higher prio process gets blocked for a long time in a disk wait state, suggesting that its disk I/O requests are going into the queue after the lower prio process' requests. Does anyone know if there's a way to prevent this behavior? Thanks - Mike Schwartz Dept. of Computer SCience U. Colorado - Boulder
