The theories are repeated a often but I have never seen any empirical data to back it up assuming one is setting the options I mentioned. These anecdotes usually come from servers with default settings and no attempt to tune them for the intended workloads and no capacity planning for application resources. Even OS maintainers are starting to recognize this and have created daemons such as tuned for the people that never touch settings. The next evolution will be dynamic adjustments from continuous bpf traces. I just keep it simple and avoid the circular arguments all together.
