If your application is fighting the language you've selected so hard, then maybe the language choice was a poor one to begin with. Modern C++ is a very high level language - very powerful when it's a good match for your needs. If you need zero overhead memory management then garbage collection isn't going to be the answer either - you need application specific arena allocators, reuse pools, etc. You seem to be focusing on a very odd set of performance requirements where the overhead of garbage collection is just right, C++ too inefficient, and the need to go full custom not needed.
