CPU Profiling a Ruby Application in Kubernetes
rbspy simplifies profiling for running applications. However, in cloud environments with distributed loads, a more automated solution like continuous profiling (e.g., Pyroscope) is preferable. Currently, an external memory profiler isn’t available, but the Ruby community has introduced a new tool, vernier, which could be useful for continuous profiling.

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
