lowalloc
Lowalloc is a term used to describe memory management techniques that emphasize minimizing dynamic allocations during runtime by preallocating large memory pools and serving allocations from those pools. The approach trades some flexibility for speed, determinism, and cache efficiency, making it common in performance-critical or resource-constrained environments.
Core ideas include preallocated pools, arena or slab-like allocators, and per-thread caches. Allocations are typically small
Common implementations and patterns related to lowalloc include slab allocators (fixed-size object pools suitable for many
Advantages of lowalloc include deterministic latency, improved cache performance, and reduced overhead from general-purpose allocators. Trade-offs
