> Now that the code has switched to byte buffers internally,  it should be possible to
improve read performance by reducing the number of byte array allocations.
> This patch accomplishes this by and re-using sections of a larger byte array slab.
> I've benchmarked it locally and seen a slight improvement on reads, a larger scale benchmark
should be performed.
> Also the size of a slab can be configured in cassandra.yaml
