Currently one can set nice value to the process. But it only affects the CPU scheduling, so if this process is CPU bound it would yield to others. What if the process is disk-bound, like some backup operations? The backup copying large disk seriously affects performance of all other apps accessing the same disk. Is there a way to set the priority value on the process for the disk operations, so that all disk operations originating from the process will be scheduled in similar way how CPU is scheduled based on the nice value of the process? The disk-intense backup process with low disk priority won't affect the other processes at all. Yuri
