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.

Help with Rust Program performance
On top of others' specific recommendations, don't forget to profile! Tools like perf on Linux and pprof within Rust will tell you which functions are taking the most time.

CPU Profiling in WSL-ish setup
https://github.com/tikv/pprof-rs: Seems to work nicely per se, but I cant seem to find any useful information in the flamegraph for my setting. I see mostly functions in std::thread but cant find the time it costs to render stuff or to do the actual computations which should be the most time consuming things. Not sure whether this is necessarily something wrong with pprof-rs, maybe I'm just bad at finding stuff in the flamegraph svg or bevys ECS is making this hard.

Does rust have a visual analysis tool for memory and performance like pprof of golang?
Have you looked into using pprof?

Pyroscope Profiler 0.5 released
The library doesn't actually do any profiling (The profiler for Rust is pprof-rs: https://github.com/tikv/pprof-rs) but it's goal is to manage data returned by profilers (abstracted behind a Backend) and send this data to a Pyroscope Server (or exported to flamegraph, though this is being implemented in the commandline application).

Rust support for continuous profiling added in Pyroscope v0.10.2
The libunwind part is actually not related to overhead, this is just a nuance of the way that pprof-rs unwinds stack traces.

Does rust have a visual analysis tool for memory and performance like pprof of golang?
1 for cargo criterion, + iai for the same author and I took memory profiler out of rust-analyser, but it has a dependency on jemalloc. Originally I was looking for a visual memory analyzer, but my current thinking that smaller, self-contained tools which can be run in CI like iai are more practical.
