   I would suggest sticking with `read/writeLongViaLocalBuffer` since read/write calls can depend on many layers of I/O before hitting the lowest layer so that allows us to pushdown the number of bytes we want to read/write as close to the layer doing I/O. Benchmarking using `ByteArrayInput/OutputStream` will give very skewed results.
