not having to have cake try to control the ingress also drastically reduces the
cpu load.
so if you can put AQM on your end of the link (just about any aqm, even simple
fq_codel), there is a huge win.

Kinda surprising that the plain ER-X isn't readily available. I know
Dustin used to have them, but they're out of stock. Both of them will do
just fine, but I'd probably pick the ER-X-SFP for the beefier CPU, if
only to get some extra headroom. Mind the ER-X only have 256 MB RAM and
256 MB flash, if that matters to you.
DSL tends to suck pretty (read: very) bad without proper shaping, I
know. On that note, are you planning to run an AQM on both ends of the
bottleneck, or shape ingress traffic via a IFB device? CAKE helps a lot
when running on ingress, but it can't come close to running on both
ends.

I'm actually most interested in how this works on low bandwidth accesses.
Typicaly, what can we as an ISP do to make ADSL and VDSL less sucky for
our customers. So an Edge Router PoE-5 1) or the X sfp 2) would be a
good platform for this? (Don't need the PoE or sfp, but it's the easiest
accessible version here in Norway).
Nils, very good of you to keep such packages precompiled! That will save
me a lot of time.

Emne: Re: [Cake] Recomended HW to run cake and fq_codel?
Hi Erik
I can't speak for what's "recommended" hardware for running CAKE on, but
from experience I can say that CAKE runs quite well on the EdgeRouters.
The EdgeRouter platform does not have CAKE support built-in, so I
maintain pre-compiled binaries here:
https://community.ubnt.com/topic/239619/cake-and-fq-pie-compiled-for-the-edgerouter-devices/1
In terms of expected performance, I've seen tests on the ER-Lite come
out at about ~80Mb/20Mb on a 200Mb/20Mb link. I've not been able to do
any "perf" runs on it myself, as my only one is in production. I don't
have an ER-X, but one of the guys on the UBNT forum claimed to get
~120-140 Mbit symmetric on the ER-X model.
Best Regards
Nils
