Re: [Bloat] hystart++
btw, this might make you happy. Adding about 7k devices a week, some signs it is beginning to go exponential. Got any ideas to help make it go exponential? :) http://stats.libreqos.io:3000/ On Mon, May 29, 2023 at 7:38 PM Stephen Hemminger wrote: > > On Sun, 28 May 2023 06:46:48 -0600 > Dave Taht via Bloat wrote: > > > Does a linux implementation of this exist?

Does a linux implementation of this exist?
