When constructing a heap, heapify operations are required on all
non-leaf nodes. Thus, determining the index of the first non-leaf node
is crucial. In a heap, the left child's index of node i is 2 * i + 1
and the right child's index is 2 * i + 2. Node CAKE_MAX_TINS *
CAKE_QUEUES / 2 has its left
CAKE is in! Great job, Dave.

Dave,
thanks for asking - I'm not an NQB author, and my know-how on Linux QoS / Cake
is fairly zero. Did you want to address Greg?
I myself am still struggling to understand how NQB operates. I understand the
idea behind it, but questions on operation still remain.

iperf 2 uses responses per second and also provides the bounce back
times as well as one way delays.
The hypothesis is that network engineers have to fix KPI issues,
including latency, ahead of shipping products.
Asking companies to act on consumer complaints is way too late. It's

Dave and Luis,
Do you know if any of these tools are using ~random payloads, to defeat
compression?
UDPST has a CLI option:
(m)-X Randomize datagram payload (else zeroes)
When I used this option testing shipboard satellite access, download was about
115kbps.

Quick note from reading your blog entry.
Last night, I played with the Cloudflare Speedtest a little. It downloads
25MB and a 50MB (or 100MB, can’t remember) as well on a “speedier” network
after it does the 10MB file.
I was getting 1.2Gbs down and 760Mbs up, 4ms of LUL, and seeing those

yeah, I'd prefer not to output CLT sample groups at all but the

them. I thought about providing a distance from the gaussian as output
too but so far few would understand it and nobody I found would act upon
it. The tool

For responsiveness, the bounceback seems reasonable even with upstream

Some thoughts are not to use UDP for testing here. Also, these speed
tests have little to no information for network engineers about what's
going on. Iperf 2 may better assist network engineers but then I'm
biased ;)

Seems to me that we often get distracted by nomenclature needlessly.
Perhaps it's time to agree on the lexicon that should be used going forward
so as to avoid such distractions.
Perhaps a place to start is "the technical facts":

_[RR] ... IMO, a more useful concept of latency is the
excess transit time over the theoretical minimum that results from all
the real-world "interruptions" in the transmission path(s) including
things like regeneration of optical signals in long cables, switching

We are collecting anonymized data, but we haven't analyzed it yet. If we get a

I think Tech Quickie is part of Linus Tech Tips (Linus Media Group), not
