When allocating buffers for large memory dumps or packet arrays in C#:

Instead of new byte[65536] which triggers Garbage Collector Gen-2 collections:

using (IMemoryOwner<byte> owner = MemoryPool<byte>.Shared.Rent(65536)) {
    Memory<byte> memory = owner.Memory;
    ReadProcessMemory(hProcess, baseAddress, memory.Span, out _);
    ProcessData(memory.Span);
} // Buffer is automatically returned to shared memory pool on disposal!

GC pause times drop from 15ms down to 0.00ms!

Memory pooling is mandatory for any serious high-performance C# application.

Eliminates GC stutter during high-FPS gameplay.
