Now I have them, so it=E2=80=99s just a matter of setting it up aga= in... Cool. Another idea for a test is a real torrent or 5 of a really big well distributed file on one etherport, while a set of hosts do normal-home like things on the other, with cake unlimited vs fq-codel, and bandwidth limited for both. We don't have good numbers for cake at line rate in a scenario where we can dump 2Gbit into 1 in the real world. --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
