Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. Colleagues/Internet I love using [Linux performance tools]. CPU profile Understanding a CPU time should be easy by comparing [CPU flame graphs].
