Now I'm confused. In the guide it says to keep max-epoch-size and
max-buffers the same for best performance, while the manpage states to keep 
unplug-watermark the same as max-buffers. Which one is it? 
Or is the conclusion to keep all of them at the same value? ^o^

Still searching for those elusive 70MB/s that are lacking from setup with
a 200MB/s IO subsystem and a 3.4Gb/s network link.
