IMHO, perf's decision to write whole stacks directly to the disk and unwinding them as a post-process is a really bad design. It wastes disk space, and as the author pointed out, it also has a lot of IO overhead.

As an alternative approach, https://github.com/mstange/samply processes data streamed from perf and unwinds it in realtime. The unwinding overhead is surprisingly low: it only takes around 1% of (single) CPU per CPU profiled. Solving the disk waste alone has been a tremendous improvement of profiling experience. As a bonus, the unwinding and symbolization works reliably while I frequently had postprocessing not terminating when using the perf CLI directly.

Carbon is absolutely amazing. They are using a very flat style in pursuit of a modern corporate brand, just like a lot of other tech companies today, but the design also incorporates a lot of traditional and familiar elements. It’s a rare instance of flat UI that does not feel mobile oriented and half assed on desktop.

Carbon components are also the most accessible component set I have seen, and they go through great lengths doing automated and manual accessibility testing.

The library though, is a bit lackluster. It’s tailored for IBM’s internal need, and is still a bit far from a complete framework. So you need to be prepared to write some CSS as well as designing your own components when you need one.

Author here. Your understanding is right, and I meant that old congestion control algorithms was only using the information of packet losses.
