[PATCH 21/24] sysctl: ipv6: register addrconf tables as private children
From: Lucian Adrian Grijincu
Date: Fri Apr 01 2011 - 22:55:54 EST
This halves the time it takes to add an interface:
$ time modprobe dummy numdummies=$n
Without 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
With this patch:
- n=5000 => real: 4:43m, sys: 4:32m
- n=2000 => real: 0:39m, sys: 0:39m
- n=1000 => real: 0:07m, sys: 0:07m
