perf: unnecessary array clearing in BatchArena pool return 3 months ago

AI Summary: The `BatchArena.ReturnToPool` method unnecessarily clears large byte arrays (1MB+) when returning them to the shared `ArrayPool`, consuming 0.10% exclusive CPU. This clearing is redundant because the data is not sensitive and the buffer will be fully overwritten on its next use. The proposed fix is a one-line change to disable array clearing.

Complexity: 1/5

Performance: byte[] allocation in SendSaslMessageAsync 5 months ago

AI Summary: The `SendSaslMessageAsync` method in `KafkaConnection.cs` allocates three `byte[]` arrays during SASL message exchanges, which occur only during connection authentication. To reduce these avoidable memory allocations, the issue proposes using `ArrayPool<byte>` to rent and return temporary buffers.
