the thread responsible for network goes crazy in team games

[SeraphimLeftNut]

Do others see this behavior is this normal?
Besides the ren and sim threads which take most of the cpu load there is also another thread which gets a lot of load especially in team games like setons.
You can spot it by seeing that it is assigned to the last core(4th core if 4 core 8th core if 8 core processor) and the fact that it is assigned high priority.
The amount of load it gets is also affected by parameters such as net_senddelay and net_ackdelay(if they are made very small the thread gets more load), basically the more packets fa sends out the more load there is on the thread.

I haven't been able to play any team games for over a year because of this kind of behavior from FA, so any suggestions are welcome.
