Re: cgroup & net_prio

["S. Sakar" <mrserkansakar@gmail.com>]

Higher numbers denote higher priorities. By the way, net_prio seems to be really simple compared to tc traffic shapping. E.g.

#!/bin/sh

set -e

set -x

APPS="chromium iceweasel rdesktop"

DIR="/sys/fs/cgroup"

grep net_prio /proc/mounts > /dev/null 2>&1 || \

        mount -t cgroup -o net_prio net_prio $DIR

[ -d $DIR/high ] || mkdir $DIR/high

cd $DIR/high

echo "wlan0 10" > net_prio.ifpriomap

for pid in $(pidof $APPS); do

        echo $pid > tasks

done

Hi,

the kernel documentation doesn't seem to state whether the priorities
for cgroup/net_prio are like unix process priorities or not. The default
prio is 0 and I'm not sure if increasing the numeric value also
increases the priority. My short tests are inconclusive. E.g.:

echo "wlan0 5" > net_prio.ifpriomap
