Avoid “new” in Loops with Object Pooling

- 24.01.26 - ErcanOPAK

Heavy loops + object creation = GC pressure.

var pool = new ObjectPool<MyDto>(() => new MyDto());

var obj = pool.Get();
// use obj
pool.Return(obj);

Why it works:

  • Reuses memory

  • Reduces Gen0/Gen1 collections

  • Stabilizes latency

Perfect for:

  • Parsers

  • Serializers

  • Message processing

This is how you make C# behave like systems code.
