I'm sure this delivered large performance improvements and I wouldn't try arguing against it. Only in extreme circumstances does the cost (in processor time and I-cache footprint) translate to a tangible benefit - circumstances which usually resort to hand-coded assembly anyway.

A service team was debugging a performance issue and noticed it coincided with a high rate of paging. I was asked to help, and used a variety of performance tools to solve this including those that use eBPF and Ftrace. Reads usually have apps waiting on them; writes may not (write-back caching). Counting cache functions.

Reads usually have apps waiting on them; writes may not (write-back caching). These are rough notes.
