When you do your tests, do you set the sh= aper to a high number and see how high actual throughput goes, or do you do= it some other way? Just in case, I tried setting the ER-X to 350Mbit. htb+= fq_codel topped out at 149Mbit, and with c/burst 96000 186 Mbit, so in both= types of tests it was about a 25% increase, not small, but unfortunately n= ot 2x! > > Pete > --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
