Oh, I just had a thought, increase the RX processing limit,
that only allows you to process 100 packets in one pass.
First change it to 250 and see what it does, you might
also set it to -1 which will allow you to process til you
drain the ring, the risk is that you cause other problems
by doing that, but heck at this point anything is worth
trying, right?
Nothing has helped. :(
I need to unplug and plug in again patch cords each time when my CPUs
with emX go 100% in order to keep my server alive with a descent pings.
I mentioned that "100%: emX taskq" occurs only on that interfaces where
GRE packets are being processed.
External interface to Internet feels great. Pings are <0ms and load is
9.57% with 14kpps (input/output).
Maybe interesting:
According to kgmon:
% cumulative self self total
time seconds seconds calls ms/call ms/call name
39.9 93.10 93.10 1643247 0.06 0.07 rip_input [10]
Is it em related or mpd related or something else?
Back to releng_6? Not sure though. :(
Now I'm on 6.3-STABLE:

The results aren't good as well.
