I disagree.  If you look at Joseph Mack's throughput analyasis of the
different methods, you'll see that efficiency is effected only when you use
two redirects.  I suppose if you had TONS of small packets (abnormal
amounts) then perhaps there might be an effect.

I would be interested in seeing some kind of actual performance indication
if you have proof otherwise, since I am running the horms method here.

gracias & good weekend to you all.
