Anyway, I would also like if my ER-X (32-bit mips) had some mor= e headroom to run something codel-like. It can do it, but it starts to stru= ggle. Mine is currently an htb+cake setup. well, how much cpu can you claw back with tbf + fq_codel? note that tbf IS sensitive to the burst size. 64k might be too much.

Perhaps my understanding of what that does and use of t= he term =E2=80=9Csmp=E2=80=9D was loose... --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
