Spotting and Avoiding Heap Fragmentation in Rust Apps
I'm not sure if it's widely used, but Mesh is a C/C++ library that can recover from memory fragmentation. The YouTube video in the README is a great watch.

Bizarre memory leak caused by tokio runtime
With everyone talking about memory fragmentation, I'd like to mention Mesh, an allocator that can compact aka defrag the heap without any help from the program or compiler. Here's the talk explaining it, "Compacting the Uncompactable" by Bobby Powers.

Switching to jemalloc or mimalloc doesn't improve the performance either.

Replacing musl's malloc with mimalloc: any ideas?
mimalloc: mimalloc is an open source implementation of malloc, currently the best performing allocator.

Reptar
Some compiler writers thought that was the case, if [0] is related to OP. I don't have a "modern" (after 6th gen) Intel CPU to test it on, but note that most programs are compiled for a relatively generic CPU.

Is the JVM a upside or downside to Scala?
Yes, it's very efficient and that's not where the main problem lies. However, small allocations with modern C heap allocators like mimalloc or snmalloc has gotten extremely efficient as well. Would be interesting to see a benchmark comparison with Java's G1 and ZGC.

Z Garbage Collector: The Next Generation
Memory management for C is not itself a solved problem, not only is there a lot of performance to squeeze out of malloc itself (the benchmarks on https://github.com/microsoft/mimalloc exemplifies the variance between the implementations), but it's up to the programmer to implement memory management in the large in an efficient way, which is not an easy task. One sure mark of a slow C program is one with a ton of mallocs and frees strewn all over.

Linux Tech Tips EP#13: Testing Transparent Huge Pages and Cryo Utilities in Gaming | 3700X 6600XT
It's a very terse howto for replacing Factorio's memory allocator with Microsoft's mimalloc, and configuring mimalloc so that memory is always allocated on huge pages by using madvise().

Differences between Lean4 and Koka reference counting
I was wondering if Koka's perceus referencing counting style is any different from the reference counting that Lean4 implements? I understand that both rely upon the mimalloc (https://github.com/microsoft/mimalloc) library in the backend.

pmr implementation in c++14
If you are fine with heap allocations then there are only few dozens operator new/delete to override to regain control over normal C++ code memory use. Allocators and STL all need to call those. At least that's what gaming does on all platforms. If you need examples you can check Mimalloc on github ( https://github.com/microsoft/mimalloc/blob/master/include/mimalloc-new-delete.h ).

GitHub link to an Arma 3 allocator which increases performance by 20-50%
What's the difference between this and Microsoft's? https://github.com/microsoft/mimalloc
What are some alternatives?
When comparing Mesh and mimalloc you can also consider the following projects:
jemalloc
memory - STL compatible C++ memory allocator library using a new RawAllocator concept that is similar to an Allocator but easier to use and write.
rpmalloc - Public domain cross platform lock free thread caching 16-byte aligned memory allocator implemented in C
o1heap - Constant-complexity deterministic memory allocator (heap) for hard real-time high-integrity embedded systems. There is very little activity because the project is finished and does not require further changes.
snmalloc - Message passing based allocator
rmm - RAPIDS Memory Manager
rust - Empowering everyone to build reliable and efficient software.
tbb - oneAPI Threading Building Blocks (oneTBB) [Moved to: https://github.com/oneapi-src/oneTBB]
ixy-languages - A high-speed network driver written in C, Rust, C++, Go, C#, Java, OCaml, Haskell, Swift, Javascript, and Python
