High-Performance Object Pool Design and Implementation

The article presents a high‑performance, thread‑safe object pool that combines thread‑local freelists, a global pool, and cache‑line‑aligned structures to reuse expensive objects, dynamically expand capacity, and achieve 50‑70% lower allocation latency than standard malloc/free and existing pool implementations.

Why Standard malloc Slows You Down and How Custom Memory Pools Supercharge Performance

Although malloc is a universal allocator, its lack of scenario-specific optimization makes it unsuitable for high‑performance server applications; this article explains malloc’s internal workflow, compares it with custom memory‑pool techniques, and details various pool designs, thread‑safety strategies, and an interesting cross‑thread free problem.
