I find it very handy to show the average delays in milliseconds. Example output (on 100 concurrent dd reading sparse files): CPU count real total virtual total delay total delay average 986 3223509952 3207643301 38863410579 39.415ms IO count delay total delay average 0 0 0ms SWAP count delay total delay average 0 0 0ms RECLAIM count delay total delay average 1059 5131834899 4ms dd: read=0, write=0, cancelled_write=0 Signed-off-by:
