Nice page, but one thing i do not get is the following.

[quote]
If you compare FreeBSD / GCC 4.2.1 against, for example, Ubuntu / GCC 
4.7 then the results are unlikely to tell you anything meaningful about 
FreeBSD vs Ubuntu.

That is a little strange in my opinion.
It tells me that FreeBSD falls more and more behind on Linux.
The reason is or could be that FreeBSD cannot or will not include GCC 
4.7 and that FreeBSD will not be on par with Linux anymore.
To compare it with Formula1 cars.
If Mercedes decide to use the engine from 2 seasons back (the engine 
version 4.2.1) in there 2012 car, and Ferrari uses there new Engine 
(version 4.7).
Can we not compare them anymore because of the decission from Mercedes 
to use the old engine?
No we just say, if you want to win a race, get the Ferrari.

It is the reallity, FreeBSD uses 4.2.1 as there compiler!!!
If you tune up FreeBSD to use the GCC 4.7 compiler, or downgrade linux 
to 4.2.1, then that will tell me nothing about FreeBSD vs Linux.

I my opinion, you benchmark the latest release of Linux, FreeBSD, 
Solaris, Windows and whatever OS you want to compare!
You want to benchmark the release and not a tuned version against a 
standard version.
And that in general are the versions most of us users will use.

And what if in the future LLVM gets on par with Linux, is it stil fair 
to compare FreeBSD with Linux?
Or do we say, well we are on par, but it is not fair, yes we used the 
latest releases, but you can not blame Linux because they are still 
using GCC.
No what we will see then are haleluja blogs that FreeBSD is on par with 
Linux.

For me peformance is not a show stopper, and for the most of us i think 
it is not.
FreeBSD for me is a clean system that does the job perfect and has a 
very helpful community.
