Hi, i'm using lxc in my project, i want to control disk io speed, so i use
blkio.weight, but the result is confusing.
I create 2 containers lxc1 and lxc2
lxc1: lxc.blkio.weight=100; lxc2:lxc.blkio.weight=1000
the running scripts are same in lxc1 and lxc2:
sync
echo 3 > /proc/sys/vm/drop_caches
dd if=/var/a.img of=/dev/null bs=1M count=2000
I have read [1], and I check the io scheduler:
noop anticipatory deadline [cfq]
I suppose that lxc1 is slower than lxc2, but the test turn out that they are in
same speed.
Can you help me figure it out? Thank you.
PS: my kernel is 2.6.32, lxc version is 0.9.0
