A C++ library implementing several custom memory allocators (linear, stack, pool, and free list) as faster alternatives to malloc/free. It includes benchmarks comparing time and space complexity of each allocator.

Use cases

• replace malloc with a faster custom allocator in C++
• implement a pool allocator for fixed-size objects
• learn how memory allocators work internally
• benchmark allocator performance against malloc
• reduce allocation overhead in a game engine
• manage dynamic memory with a stack allocator

When to choose

• you need fine-grained control over heap allocation performance
• you're learning how custom allocators are implemented
• your workload has predictable allocation patterns suited to pools or stacks

When to avoid

• you need a production-hardened, general-purpose allocator
• your project requires a widely tested allocator with long-term support
• you need thread-safe allocators out of the box
