thanks @rgnldo
"dual-srchost", from reading the man page, sounds like something that one should always use, along with "ack-filter". thanks!

Both used by default (dual-srchost is included in triple-isolate) I believe

qdisc cake 800e: dev ifb9eth0 root refcnt 2 bandwidth 17Mbit diffserv4 triple-isolate nat nowash ingress ack-filter split-gso rtt 100.0ms ptm overhead 22 no-sce
qdisc cake 800d: dev eth0 root refcnt 2 bandwidth 5Mbit diffserv4 triple-isolate nat nowash ack-filter split-gso rtt 100.0ms ptm overhead 22 no-sce

EDIT - Clarification

qdisc cake 800d: dev eth0 root refcnt 2 bandwidth 5Mbit diffserv4 triple-isolate nat nowash ack-filter split-gso rtt 100.0ms ptm overhead 22 no-sce

maybe slightly different (dual-srchost vs triple-isolate)?

from man page:

dual-srchost
Flows are defined by the 5-tuple, and fairness is applied first
over source addresses, then over individual flows. Good for use on
egress traffic from a LAN to the internet, where it'll prevent any
one LAN host from monopolising the uplink, regardless of the number
of flows they use.

dual-dsthost
Flows are defined by the 5-tuple, and fairness is applied first
over destination addresses, then over individual flows. Good for use
on ingress traffic to a LAN from the internet, where it'll prevent
any one LAN host from monopolising the downlink, regardless of the
number of flows they use.

triple-isolate (default)
Flows are defined by the 5-tuple, and fairness is applied over
source *and* destination addresses intelligently (ie. not merely by
host-pairs), and also over individual flows. Use this if you're not
certain whether to use dual-srchost or dual-dsthost; it'll do both
jobs at once, preventing any one host on *either* side of the link
from monopolising it with a large number of flows.

@rgnldo sounds like the default would be the safer choice? or dual-srchost better for asymmetrical connections?

 

[rgnldo]

with "docsis unlimited ack-filter dual-srchost" i just got 330/17 bufferbloat A on dslreports.
latency was good even with multiple clients in use.

remove ack-filter

remove ack-filter

but doesn't ack-filter help reduce UL bloat?

 

[Wade Coxon]

remove ack-filter

Isn't that setting specifically for dealing with highly asymmetric upload-constrained connections such as his?
Or does that guideline not apply once the upload is higher than a certain level?

 

[ttgapers]

I am thinking of CakeQoS as a solution for reducing latency and network congestion. For this reason I am trying to adapt the autorate-ingress solution. Who knows, CakeQoS will be an unbound or dnsmasq plugin

You never know. But we need to get more routers supported

 

[ugandy]

See

not sure i follow.
are you saying to use dual-srchost on the egress and dual-dsthost on the igress?

 

[rgnldo]

Other users need to test.

It would be your CakeQOS solution activated. Unbound is loving it, with high HIT rates

 

[rgnldo]

Take the test with the configuration I demonstrated. Then go back to yours.

not sure i follow. how does cakeos help unbound's hit rate?

 

[rgnldo]

how does cakeos help unbound's hit rate?

prioritizing query packages to remote name servers. Latency has also been reduced

will test.
"docsis ack-filter triple-isolate"(default) vs "docsis unlimited dual-srchost" ?

 

[rgnldo]

docsis

If I'm not mistaken, this is a ISP/client connectivity method. It is?

 

[ugandy]

If I'm not mistaken, this is a ISP/client connectivity method. It is?

yes. specifies the packet overhead i think. docsis is cable

just tested.
on my comcast connection, dslreports got worse UL bufferbloat when i removed ack-filter

@rgnldo what are your thoughts on triple-isolate vs dual-srchost?

 

[Jack Yaz]

prioritizing query packages to remote name servers. Latency has also been reduced

that has 0 impact on cache hit rate though....

 

[rgnldo]

cache hit rate

That's right. I wanted to inform recursive replies response time.

what are your thoughts on triple-isolate vs dual-srchost?

triple-isolate can be applied equally to both upload and download with good effect, reading the manual you'll need to apply dual-srchost to your upload and dual-dsthost to the download which needs you to edit the script.

you specifically mentioned hit rates. sometimes it's very hard to follow your posts as they jump topics at random.
