| |
This halves the time it takes to add an interface:
$ time modprobe dummy numdummies=$n
Without this patch: - n=5000 => real: 17:31m, sys 15:29m - n=2000 => real: 2:23m, sys 2:19m - n=1000 => real: 0:25m, sys 0:24m
With this patch: - n=5000 => real: 9:14m, sys: 8:46m - n=2000 => real: 1:19m, sys: 1:17m - n=1000 => real: 0:14m, sys: 0:14m
