@brainstorm this may be a good way to finally close out umccr/htsget-rs#137.

Is DHAT output compatible with the firefox profiler UI? They seem to have their own viz according to docs (see https://nnethercote.github.io/dh_view/dh_view.html), maybe I'm missing sth?

I just went ahead and removed DHAT from the title, as honestly I'm not versed enough in profiler formats to know if that's what we actually want long term. I just know that Google Trace Event format doesn't support all the things in Rust that it does for Go, so I thought maybe DHAT would be the way to go but with a very big 🤷🏽‍♂️.

Firefox Profiler does support DHAT though (bottom of https://profiler.firefox.com):

The ⁨Firefox Profiler⁩ can also import profiles from other profilers, such as Linux perf, Android SimplePerf, the Chrome performance panel, Android Studio, or any file using the dhat format or Google’s Trace Event Format. Learn how to write your own importer.

For Bare Metal Runners (#199)
Consideration using Perfetto: https://github.com/google/perfetto
It is written in C++ and will have a more consistent overhead than something written in Go like Parca: https://github.com/parca-dev/parca

Came across this recently, no idea if it's good or not: https://github.com/deepflowio/deepflow

Some non-eBPF based profilers that may be worth considering:

• Coz: https://github.com/plasma-umass/coz
• Scalene: https://github.com/plasma-umass/scalene
