There IS NO EVIL INTENTION, except, hypothetical, the benchmarker is of the age were he is called a "beardless". But: In many articles, there is a very distinguished and underlined emphasizing of Linux that makes me feeling people have their Linux-glasses on. Linux is not UNIX! And if today someone tells me about the Linux-graphical subsystem X11, I turn green in my face ... X11 was, in former days, a development made on UNIX and is adopted by Linux. Ok, we all know that, most of all ... And the aspect of reference: I agree.

FreeBSD is handled via this list since we are spread around the globe and even the developers are spread worldwide. But when it comes to detecting worse performnce and someone isn't capable of giving a detailed insight and mostly scientific way of investigating the fault he experienced, the discussion, if it starts, get drowned by allegations like "bad testing", worse optimizations blabla. Look at Steve Kargls problem. He investigated a SCHED_ULE problem in a way that is far beyond enough! He gave tests, insights of his setup, bad performance compared to SCHED_4BSD and what happend? We are still stuck with this problem and more and more people realise, that FreeBSD does have somewhere a problem and this seems to be a nasty problem not easy to find or investigate. But look at how Steve has been silenced in the past ... Benchmarks, especially published ones, reveal those pits and soemone could look into it. Another problem is this very elite-feeling closed club. Once you managed it getting into the club of committers or core team members, you'll probably fight for your seat ... I dont propose for that socialists crap Linux people tend to be like, overcrowded townhalls full of important people with non-consense opinions. The other extreme end of this spectrum. I can not change this. And I do not know whether there is a real way-in-the-middle. But I follow the illusion that if people can see what benchmarks reveal, they start thinking and if the facts are starting to give a heavy load load on those rejecting the facts, they migght change their opinion or get hopefully replaced by more openminded people.
