Well, in car NEDC testing, the car is tested as is (meaning as the car model is officially described, out of the factory). What to remove is specified in the test docs. Otherwise, no optimizations.
This is the point people seem to miss with "out-of-box" and why people care. There are plenty of users that are not interested in tuning every part of the system to get the best performance. They just want to install it and use it. As such out-of-box is very relevant. In fact if you are comparing distros that's a major part the default configuration.
Again: this is *not* (only) about *tuning*. "Tuning" would be e.g. (for the ethernet performance tests) setting net.core.[rw]mem_max sysctl, NIC offloading flags etc. I'm not talking about that. Comparing packet latencies between distribution A with connection tracking and complex set of rules against distribution B with no firewall (and conntrack) means that you are running a completely different test for each, not that you "did not tune". The same holds for the selection of services to run by default and measuring the "boot time". As I said before, we could disable everything not strictly necessary for login prompt (or sddm login screen) and we would get perfect "boot time" rank in Phoronix benchmarks. Of course, such default installation would be essentially unusable. Do we make a mistake by not going this way? I don't think so, there are more important things than rank in a pointless benchmark article.
Clearly if I try hard enough I can make distros very similar to each-other as they are running the same upstream software and as such I would get more similar results. At that point you are benchmarking the upstream software and not the distro.
Even that is not true. You would get differences from e.g. compiler version and flags, kernel configuration etc.
Crappy defaults are a serious problem, no one is expert in everything nor wants to be.
Do you call the choice to prepare firewall config and enable the firewall or to enable other services (that other distribution might not) a "crappy default"?
