Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

When counting lines in Ruby randomly failed SerpApi deployments
We used rbspy to generate the flamegraph:

EventMachine Performance Spikes
You could use rbspy to profile the EventMachine process as it's doing the workload, and try to see there where most of the time is being spent.

Rails Resque - AWS ECS task randomly stuck
Not sure what your issue is and you got some of this info from strace, but FYI rbspy can also help profile where a running Ruby process is spending its time: https://rbspy.github.io/. I think it's a little more helpful than strace in that it should bring it back to Ruby code rather than just showing the raw syscalls.

Optimizing your tests in 5 steps
Even the most general profiler tool will show you each statement's accumulated time. These are called statistical profilers and give you a panoramic view of what the test is doing. An example of such a profiler is rbspy:

Fantastic Symbols and Where to Find Them - Part 2
As a result, you need to craft a specific routine for each interpreter runtime (in some cases, each version of that runtime) to obtain symbol information. Educated eyes might have already noticed, it's not an easy undertaking considering the sheer amount of interpreted languages out there. For example, a very well known Ruby profiler, rbspy, generates code for reading internal structs of the Ruby runtime for each version.

How to use strace on threads managed by supervisor? i.e. i want to ´supervisorctl restart someService´ and strace someService.
For production, it depends on what the process is built with. There are possibly better tracing tools than just strace. For example Java has JMX, Go has pprof. There's also things like rbspy for Ruby.

Why Is JRuby Slow?
I was a bit surprised to find out that the tool used to generate the flamegraph for Ruby (rbspy [1]) is written in Rust. lol

Profiling Rails app that uses websockets
Maybe https://github.com/rbspy/rbspy would allow you to profile the running ruby process handling web sockets?

How SerpApi sped up data extraction from HTML from 3s to 800ms (or How to profile and optimize Ruby code and C extension)
c function is not very helpful to find the performance problem, so we dug deeper.

Flameshow: A Terminal Flamegraph Viewer
There is a "live" flamegraph TUI that uses Austin for those interested in Python profiling https://github.com/P403n1x87/austin-tui. The data collected can be exported and then converted into pprof, and analysed further with flameshow etc...

Austin – Python Frame Stack Sampler (or zero-instrumentation profiling) 2.1.1
- Scoop
Austin is also simple to compile from sources as it only depends on the standard C library, if you don't have access to the above-listed repositories.
This new release of Austin brings enhanced support for many Python binary distributions across all the supported platforms, as well as a bugfix for the line number reporting. If you rely on Austin 2, upgrading to the latest version is strongly recommended.
Let me also remind you of some of the other existing Python tools powered by Austin, which have also seen new releases in the past few days, and that are easily available from PyPI:
