Change subject: KUDU-1865: Avoid heap allocation for payload slices ...................................................................... KUDU-1865: Avoid heap allocation for payload slices As shown in KUDU-1865, the heap allocation for the temporary vector for the slices for holding the serialized payload is introducing measurable overhead under heavy load. This change replaces the heap allocation with a stack allocation of an array of size TransferLimits::kMaxPayloadSlices. With this change, we saw 10%~15% improvement under heavy workload.
