mmm, for polling you need to use PollDevice instead of FromDevice and I
think the Print(ok) does also insert a big delay if you do this for each
packet (logging to syslog).

simply use counter, it will also calculate the rate for you.

Just use e.g. PollDevice(eth1,1) -> Counter -> ToLinuxSniffers();

We are also interested in your results, so if you could post something
if you have interesting (faster :-) ) results. I have tried the same but
only on a singleprocessor for now (multiprocessor would be done in a few
weeks) and there I thought indeed the click-tcpdump was slower because
click takes all processing power.
