Detailed Description

Selective simplified memory pool with optimized performance.

Core design principles:

• Small pools: Lock-based (fast allocation, low overhead)
• Large pools: Lock-free (high concurrency)
• Memory alignment: 64-byte alignment for buffers >= 4KB
• Minimal statistics: Basic stats only to minimize overhead
