I'd be interested to see results from pre-CFS kernels.
Not that FreeBSD hasn't made major performance improvements.
Also, I think that a database test isn't a complete picture. For example, some OSes like IRIX or Mac OS X perform very well on streaming of local video and audio, but I wouldn't benchmark Oracle or PostgreSQL on either.
Yes, I meant that: who cares? Nobody living outside their parents' basement is going switch from Linux to BSD for a 15% performance increase. Somebody already using BSD might upgrade if the latest BSD kernels and environment are significantly better than past environments, but 15% is so slight as to be basically undetectable in a real-world environment!
My rule of thumb for upgrading equipment has been to not bother until we hit a full order of magnitude improvement. In other words, if 1) we can 10X the perfo

Obviously, it depends on cost:benefit, which is exactly why there is no rule of thumb. Blanket generalisations and "rules of thumb" are a bad way of making a decision for everyone that they don't need to make
That isn't the important point though; the important point raised is that CFS might be less good than promised and that there's the accusation that Linus picked CFS over other projects because Ingo is in the in-crowd. I don't follow lkml, so I wouldn't know whether this is true.
