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 to Perf profile functions?
For accurate memory usage I prefer a memory profiler that overrides malloc and friends instead of the ones that probe the OS at regular intervals. You won't find memory spikes with the latter. Try heaptrack on Linux. I haven't found a good one for Windows yet.

What is your favourite profiling tool for C++?
I know it is not a profiler, but it is so criminally underrated that I decided to share it: https://github.com/KDE/heaptrack

My Rust program (Well, game) is leaking memory, 4MB/s.
If none of the above helps - I recommend heaptrack as a tool for tracking down your memory usage.

> memory leaks. It's surprisingly hard to find an easy to use memory leak detection tool.
I can vouch for heaptrack[1] nowadays, although it's pretty much Linux only. It's under the umbrella of KDE, but a heaptrack trace only requires a CLI app, and there is a nice Qt viewer to analyse the memory consumption.
It tracks the memory utilization at the level of malloc'd/free'd bytes. It's fine if your memory leak or other memory utilization problem is on this level. Recently I dealt with an issue, where increasing memory utilization was caused by fragmentation within the allocator. This didn't show up in heaptrack as an increasing memory utilization, but heaptrack still pointed out where most of the temporary allocations happened, leading to the culprit of the fragmentation.

Memory Leak? Free memory not being reclaimed? What is happening here
When I had this kind problems (heap related) I always use heaptrack. Take a look here for the details: https://github.com/KDE/heaptrack
- Hi, I’m new in rust, I have some expirience with c# and its classes ans structs. I can’t find information about that is happend with struct in rust when I pass it to function argument. Are there some copy effect ?

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.

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.

How to identify inefficient method calls?
If you are uncertain about the performance characteristics of a function you should ALWAYS benchmark it. Googles Benchmark library is wonderful for quick micro benchmarks. For more complex things, perhaps look into profiling and then look at invocation counts of copy constructors.
-
Is there any fast allocator in std lib / boost for fixed size objects (not at compile time) but has deallocation methods?
Your compiler may be optimising away your loop, there. I typically use a micro-benchmarking tool for these types of tests. You could try Google Benchmark. It’s available in most OS’ package managers, but pretty easy to build from source if not

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.
