Subject: [Bloat] benefits of ack filtering
Date: Tue, 28 Nov 2017 13:48:31 -0800	[thread overview]
Message-ID: <CAA93jw47ZAXAJmiOVCb2NR3JRcCfmX0TLr+55O0G+J6HCW5bVQ@mail.gmail.com> (raw)

Recently Ryan Mounce added ack filtering cabilities to the cake qdisc.

The benefits were pretty impressive at a 50x1 Down/Up ratio:

http://blog.cerowrt.org/post/ack_filtering/

And quite noticeable at 16x1 ratios as well.

I'd rather like to have a compelling list of reasons why not to do
this! And ways to do it better, if not. The relevant code is hovering
at:
