Hi Martin,
These may be the patches I did some very basic testing (and readprofile
profiling) on.
http://www.filip.sneppe.yucom.be/linux/netfilter/performance/benchmarks.htm
I don't have a lot to add to the discussion except that I can make time
to test patches/ideas provided someone tells me *how* to test, what to
look for, etc. For instance, a lot of the current numbers on that page
with the varying mtu sizes are, in retrospect, basically stupid tests
that don't reveal a lot of new stuff :-/.
