Not specifically addressed at you, but it's a bit amusing watching a younger generation of programmers rediscovering things like this, which seemed hugely important in like 1990 but largely don't matter that much to modern workflows with dedicated APIs or various shared memory or network protocols, as not much that is really performance-critical is typically piped back and forth anymore.
More than a few old backup or transfer scripts had extra dd or similar tools in the pipeline to create larger and semi-asynchronous buffers, or to re-size blocks on output to something handled better by the receiver, which was a big deal on high speed tape drives back in the day. I suspect most modern hardware devices have large enough static RAM and fast processors to make that mostly irrelevant.
