It's tempting to go down the rabbit hole of getting creative with memory management as the author does, and maybe worthwhile for educational purposes, but has anyone here observed any noticeable performance gain from it? My impression is that libraries like mimalloc and tcmalloc are painstakingly optimized by specialists and unlikely to benefit from any casual embellishments beyond using the supported malloc and free functions for everything. What does the HN braintrust recommend?
