Profiling by thread

Hello Community,

I am developing a multi-threaded rust application where many threads continuously run a computationally heavy optimization algorithm. I am looking for performance bottlenecks in each of the algorithms, but I am having a hard time producing correct profiling information and flamegraphs.

Every flamegraph that I create always seems to be missing stack information from some of the running threads?

Does anyone know a good way of profiling threads individually in rust? Currently I am thinking about just learning perf and solely relying on that but cargo flamegraph seems a little more convenient.

Kind regards,
Christian
