@matigo I keep saying it, but I also keep getting more evidence to support my theory practically each day; new developers have fundamentally no respect for hardware!
Optimisation is an unknown phenomenon that they have apparently never heard of, and their "solution" to a slow system is to toss more hardware at it. It just doesn't sit well with me when an older system running on one server did the job fine, but the brand spanking new system running on some hundred servers is slow as molasses in winter most of the time.
