And the strangest part is: If I initiate a network traffic before logging in KDE4(usually online radio with cvlc), ping stays normal:

This is haunting me for years already. I've been through several kde4 and kernel incarnations and this problem stays no matter what. :?

I had some weird stuff like this the other day. Try setting a static ip in network manager and see if it works.

Sadly static configuration did not help, thank you Atmmac! :?

I had some really strange problems when upgrading to KDE-4.14.3 last week (mostly with akonadi semantic-desktop crap) and when I fixed the system from terminal the network was really slow. After I've got the system (=KDE) fixed everything is working fine again.

I don't think that this helps you and I don't know what was exactly causing my problems, but it was strange for me that the upgrading gui/kde could affect the network performance. Only thing I found with top was that while the CPU usage was low there was very high ~99% wait and lots of I/O with plasma/icon-cache files in /var/tmp/kdecache-user/ folder.

Thank you linuxtuxhellsinki!

I found the issue! It was the pulseaudio hogging the network! :x

One of these usefalgs was responsible: gnome libsamplerate realtime lirc :!:

socket-sentry is really a useful tool. ;)
