Inside CPython’s Memory Manager: How PyMalloc Handles Small Object Allocation

This article explains CPython’s three‑layer memory allocator, PyMalloc, detailing how it organizes blocks, pools, and arenas to efficiently serve thousands of tiny object allocations while minimizing fragmentation and falling back to the system malloc for larger requests.
