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.

- How can I check the execution time of a program rendered in SFML?
-
How to Perf profile functions?
You can also use a benchmarking library like Google benchmark or similar.

how do you properly benchmark?
I'm aware of one by Google that I used a couple times, but IMO it's better to capture real runtime data from a fully-operational process than to carve out the benchmarkable bits and test them in isolation, so I track information during program testing and print it all to a log instead of using things like that.

Benchmarking my data structure
If you just want to do some quick benchmarks, you can just use std::chrono::high_resolution_clock::now(). Call it before the code that you are benchmarking and then immediately after. Take them away and you have your duration. If you want to use a proper benchmarking tool then I can totally recommend Google Benchmark. Fantastic benchmarking tool. Honourable mention would be Quick Bench which is an online tool that uses Google Benchmark.
- Best accurate way to measure/compare elapsed time in C++

Don’t Be Scared Of Functional Programming
We don't know if it's a lie until we verify it and that's not difficult, you have a quicksort implementation in a couple of languages, you'll need to pass the necessary parameters to show the time needed by a function call to execute to the compiler or interpreter or you may use use a library(like benchmark for C++) and you're good to go.

Calculate Your Code Performance
C++: C++ has quite a number of benchmarking libraries some of the recent ones involving C++ 20's flexibility. The most notable being Google Bench and UT. C does not have many specific benchmarking libraries, but you can easily integrate C code with C++ benchmarking libraries in order to test the performance of your C code.

CXXGraph Library Release v0.1.5
# Check out the library. $ git clone https://github.com/google/benchmark.git # Benchmark requires Google Test as a dependency. Add the source tree as a subdirectory. $ git clone https://github.com/google/googletest.git benchmark/googletest # Go to the library root directory $ cd benchmark # Make a build directory to place the build output. $ cmake -E make_directory "build" # Generate build system files with cmake. $ cmake -E chdir "build" cmake -DCMAKE_BUILD_TYPE=Release ../ # or, starting with CMake 3.13, use a simpler form: # cmake -DCMAKE_BUILD_TYPE=Release -S . -B "build" # Build the library. $ cmake --build "build" --config Release # install library $ sudo cmake --build "build" --config Release --target install
