getdelays: show average CPU/IO/SWAP/RECLAIM delays
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
