A curious case of O(N^2) behavior which should be O(N) (2023)
The timeline view in the upper screenshot is fairly straightforward: the region of 28-53s is selected, other parts of the timeline are grayed out, and the statistics for the selected time region down below show 94.4% of "Total CPU" being in id_sort_by_name.
The lower screenshot is a flame graph. If you haven't encountered one of those before, it's totally reasonable to not know how to read it. But it's a standard and common way to present this sort of data. See https://www.brendangregg.com/flamegraphs.html for more information.

Page Sized Writes
Looking at the result for aligned writes, it takes 6.3s in total to complete. Of this, 0.3s is used in user land with 6s used by the system in kernel space(syscalls). In order to make sense of the results, I profiled and collected the stacks traces for analysis. The call stacks can be visualized in the flamegraphs as shown below

Ask HN: Going low-level – what to learn next?
If you want to "go low" in the operating system, you could write a Linux kernel module:
https://sysprog21.github.io/lkmpg/
https://blog.sourcerer.io/writing-a-simple-linux-kernel-modu...
If you want to "go low" in the way hardware works, you could try and write an interrupt handler on an embedded device.
If you want to "go low" in how optimizations work in application development, you could try and implement microbenchmarks and look at flamegraphs.

All my favorite tracing tools: eBPF, QEMU, Perfetto, new ones I built and more
which can output in a format understood by Brendan Gregg's flame frames (https://www.brendangregg.com/flamegraphs.html)
But that's not quite the kind of tracing you're talking about. We also built a printf-style interface to our recording files, which seems closer:

Recap of Werner Vogels' Keynote at re:Invent 2023
Strategies included discontinuing or resizing underutilized services, transitioning to more cost-effective solutions, reducing the current resources to the amount of resources that we need for our application, and conducting detailed analyses of computing resource utilization through tools like flamegraphs. This detailed scrutiny helped identify and rectify significant cost-driving areas, such as garbage collection and application configurations.
