I'll get to queues eventually. Right now I precede this pipe with a pipe that
reports overall statistics for tcp/udp/other and one that develops statistics
and applies 128kbps bw limits on a per source host basis. All pipes are

Yes, when I do this with an 8 sec delay to reading, I sometimes catch a
dropped packet. Calculated bw is ~200kbps. After some minutes it goes to the
1% level and stays there.

Yes, everything seems to be consistent and counts match closely.
It's not so much a problem but that I am curious. And, I still don't
understand the significance of the ip addresses/ports shown in the single
