while playing urban terror i noticed several lags. So i tried to find out where the problem is.
iftop says something makes multicast calls all the time. So i disabled it with
- Code: Select all
sudo ifconfig wlan0 -multicast
sudo ifconfig wlan0 -allmulti
But it looks like it didn't help. Then i disabled avahi, which didn't help either. Some retarded program is still killing my ping.

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd
