We can also use vector instructions on the batch of tuple, which reduces overhead by requiring fewer function and instruction calls.
Of course, the limitation here is that the hardware needs to support vector instructions, though nowadays that is hardly an issue,
since AVX instructions are supported on CPUs as old as the Sandy Bridge Architecture (e.g. Intel Core i7-2600K) for Intel (2011) and Bulldozer (e.g. AMD FX-8100) for AMD (2011).
