Well, man 1 ionice describes it pretty clear, isn't it? Class 3 (-c3 option) stands for "Idle", which means that program will use disk only when others doesn't use it. As stated in man page, "The impact of idle io processes on normal system activity should be zero", so any other program would have normal access to disk at full speed (unless there are other processes using disk right now). -- Regards, Alexander Batischev 1024D/69093C81 F870 A381 B5F5 D2A1 1B35 4D63 A1A7 1C77 6909 3C81
