[SR-Users] RTPEngine performance - How far are you pushing your systems

[davy van de moere]

As an update, I'm getting 2000 channels in kernel mode, with about 50%
usage of 1 core. (load of the server is at 0.5), which is a 10 fold
difference.

The problem I was hitting, was the (probable) inability to work in
kernelmode with the rtpproxy.so module, rtpengine.so works nicely.
