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.

A fast, single queue thread pool created with C++20
Benchmarks is indeed a good question. Here is a C++17-style library for parallel function calls which avoids std::{function, future, promise} and uses disposable threads for running the functions. I have run a few benchmarks against a typical thread pool which uses a mutex and a condition variable and a vector of threads.

You might consider using this header-only library.

Does Execution Policy in std::transform in gcc have any effect?
Using Lazy the simple header-only parallel library found here in Github.

Therads in Cpp
Unless you really want to play with "raw" C++ threads, you may be able to completely avoid them by using a library like this one. See the simple examples on the main page and check if they would suit your application.

How to force your code to use all CPU cores? In an efficient manner.
This header-only library might come in handy when experimenting with parallel functions. You can run any number of functions in parallel and gather the results conveniently. Take a look at the examples on the main page in Github and see if you find them useful.
