Thank you for contributing to the discussion. I agree that the page I
cited lacks a lot (I mentioned it), but unfortunately that's the best
one I could find that touches the subject. Naturally a benchmark would

myself now.

I don't think the article is about the same thing we're talking here.
CONFIG_PREEMPT* options control the compromise between latency and
throughput of *system calls* and *scheduling of CPU cycles spent in
kernel

Since cloud images are mostly run for server workloads in headless
environments accessed via network only, it would be better if
"linux-image-cloud-*" kernels were compiled with CONFIG_PREEMPT_NONE=y
