That was dropped in the recent output change.
So if you prefer unit-less lines that's defensible, perhaps output the unit somewhere else:
syscall calls min avg max stddev (msec) (msec) (msec) (%) --------------- -------- -------- -------- -------- ------ sendmsg 2 0.002 0.005 0.008 55.00 recvmsg 2 0.002 0.003 0.005 44.00 epoll_wait 1 0.000 0.000 0.000 0.00
or so?
Thanks,
