I agree there could be more details about the specific system used.
At the same time, I'd take this as more valuable & informative than not, to be a reasonable indicator of what most users might expect. There are quite a large number of different tests features here that give quite good representation.
A lot of your questions don't seem concerning to me. Perf is just one test, and we have plenty of other great real world tests here. Kernel parameters are set at boot, and those arguments are shown. RAM isn't allocated to CPUs: there is a single I/O Die which all ram is connected to & cores access it uniformly over Infinity Fabric. There's no tuning to IRQs implied but if you have similar hardware it should reproduce without fiddling, and more so, the IRQs should be working similarly in both cases; the default config is more than good enough to compare two cases with. I would not expect ECC to make a vast difference, and it's notable that some level of ECC already is built in to all DDR5 anyhow ("ECC" is now a matter of whether the ECC extends to the CPU or is on-chip only). None of these points seem strong enough that I'd consider discarding or ignoring these findings.
This article has a pretty good starting place that paints a pretty good general picture. It's a service & contribution & informs nicely. For users who have more specific concerns, they should follow up, and ideally, do as good a favor as Mr Larabel did & blog their findings.
