[LibreQoS] [Bloat] [Rpm] [Starlink] the grinch meets cloudflare'schristmas present

[Luis A. Cornejo]

Dave,

I should be able to do that. Might be over the long weekend. I had flent
working on OS X but after an OS update something broke. My Linux box is
down.

Meanwhile in VZ HSI LTE land, got a new IP address overnight to a different
class A network, same AS, no restart. I get this:

cloudflare:

waveform:
https://www.waveform.com/tools/bufferbloat?test-id=bd07c5ed-7e38-41b0-b0db-d1325cbe189d

Not sure if they lit up a new band, or carrier aggregation or what on my
tower, they really upped the bandwidth! Along with the bufferbloat.

If I put on some SQM with CAKE:

qdisc cake 802a: dev eth2 root refcnt 9 bandwidth 20Mbit diffserv4
dual-srchost nat nowash ack-filter split-gso rtt 100ms noatm overhead 34
qdisc cake 802b: dev ifb4eth2 root refcnt 2 bandwidth 110Mbit diffserv4
dual-dsthost nat wash ingress no-ack-filter split-gso rtt 100ms noatm
overhead 34

cloudflare:

waveform:

It is almost like VZ has been tracking me and realized that they had to up
their game =P. I'll see how it continues throughout the day with this much
more bandwidth, I am more than willing to sacrifice a bit of it for no
bufferbloat. I guess I can resort to the autorate script as well if the
available bandwidth starts to fluctuate too much.
