Description
Issue: There is a lot of byte[] allocated when handling TCP messages:
It's better to have a ByteArray pool allocator so that byte[] can be reused and avoid creating massive garbage for the GC and the throughput can be even better.
For example:
ByteArrayPoolAllocator pool = ByteArrayPoolAllocator.DEFAULT
byte[10] obj = byteArrayPool.getByteArray(10);

Research direction
Start by reviewing the TCP message handling path and the proposed ByteArrayPoolAllocator example in this issue. Check closed pull request #72 for prior work on the allocator and string pool. Done means the pooling approach is implemented for the relevant allocations and its effect on garbage creation and throughput is validated.
