The edgerouter (which has fq_codel in their 1.5 firmware release), doesn't. (and it took 10 minutes to port the sqm-scripts over to it) (and I haven't got around to booting an openwrt version on it, their firmwa= re is 3.4 based) That said I am seeing stuff that indicates inbound htb is increasingly inaccurate on both products starting at about 20 mbit. (I had long assumed before now that it was a cpu limitation as I don't see this on x86) The 36mbit number you got matches mine, try increasing the rate limit to 64mbits and see what happens. Also, please measure the bloat you get on the openrg without sqm.... I would hope the downstream bloat is less horrible than cable modems. > connection, but agreed to swap my IPv4/25 for an IPv4/28. > I moved all my IPv4 to traditional NAT'ed, IPv6 all around, and /32 > routed the IPv4 to the various machines that actually need it. nifty. When I get a /29 from comcast I don't have that ability, I think. did you do that via proxy arp, or did they give you an ipv4 gateway and routed the /28 ? > The ISP (www.storm.ca.
