[Lxc-users] blkio.weight doesn't work

[陈竞]

Hi， i'm using lxc in my project, i want to control disk io speed, so i use
blkio.weight. I test it, but the result is confusing.
I create two container A and B:
A: blkio.weight = 100            B : blkio.weight=1000

the running process in A and B are the same, which is bash script :
dd if=/tmp/xxx of=/dev/null
the size of xxx is 400Mb

I suppose that A would be slower than B, since its weight is small, while
the test turns out that B run as fast as A, they are in same speed.
Can any help me figure it out ?
PS: my kernel is 2.6.32, and lxc is 0.7.5
