Superhub : Bufferbloat - is it bad?

[SnoopZ]

I consider my broadband to be working perfectly, it gives me full speed for what i pay for and currently no congestion since moving to an upgraded CMTS.

However after running the DSLreports speedtest i have been getting readings of C,D and F for bufferbloat, is this bad as based on my other graphs below everything appears to be fine apart from the TBB graph, although this is only like that as i am running on 16 downstream channels on my Hub3 since moving to an Arris CMTS and everyone experiences the same result, and i am not sure if it is really causing a problem, unless it is causing the bufferbloat?

My Sky 80mb fibre has been suffering lately imagine gaming with your kind of connection, must be awful. I'm quite literally amazing at Black Ops 3 I put most of it down to my connection with its 20mb upload.

As i said my connection is great, gaming is not an issue, so as in the OP is bufferbloat bad for the technical minded folk here who know the answer?

Bufferbloat increases download and upload speeds (by a minute amount) at the expense of poor responsiveness while maxing out the connection.

If you try gaming or browsing while also downloading or uploading at full speed, you'll notice a lot of lag. If you only ever do one thing at a time on your connection, you won't notice the effect at all.

Bufferbloat has always been bad on VM's network, it's intentional and by design.

Maybe it is the Hub3 doing it, but the connection itself currently seems 100% fine.

Mine was same on sh2, sh2ac and the sh3

[SnoopZ]

No idea here then, atleast the connection seems fine.

Fine here on the SH3 too

All i know is the bufferbloat is on my downstream, upstream is fine, the connection appears perfect though on 16 downstreams, however i was congested when on a different CMTS on 8 downstreams.

I can only comment on the TBB graph as Bufferbloat is not something that appears to affect my son's gaming while I'm busy doing other stuff.

The TBB graph on the SH2ac in modem mode to an ASUS router showed very low maximum latency. On the other hand, with the SH3 I see the same as Snoopz; perfect performance but higher maximum latency and the same as before low average latency. I'm told by VM that they are looking at this phenomenon.

My downstream seems to be iffy but upstream tests just tank it massively

Odd. The cable networks usually have bloat on upstream, not downstream.

When i do that speedtest the bufferbloat can shoot right upto 1200ms by the end of the test for download, however when doing upload it stays lowish at around 20ms if i remember, not at home so cant check.
