Ok, then FreeBSD is just slower... 
you missed the main point. The test was done with applications compiled
with unknown options. If you want to find out the impact of an
operating system on you application you have to use the same compiler
with the same options on all platforms. Basically, it was a compiler
test named operating system benchmark.

OK, now I get your point. You mean he's doing an Operative System test
using an application, that is something that involve an additional
complexity. 

I get your point, but, er... I suppose he's using pkg to install the
ports or apt-get to install the packages. I mean I suppose he's lazy
enough to compare binaries vs binaries. 

Now what you're telling me is "it's not a kernel comparison, it's an
application over a kernel comparison" and I agree with you, but why
should a casual reader be interested in a kernel comparison? Or, in
general, what would you do with a kernel without an application? :) 

Sorry, I don't want to sound polemic, neither start a flame or anything,
I'm just curious... And I understand clearly the philosophical
differences between a Base BSD system and a Linux Distribution, but
again I'm a simple person, I just stick the FreeBSD cd in, install and
then do pkg install unzip. If it's slower than my colleague using Ubuntu
and doing the same thing I just feel sad :) 

So the first outcome everyone thought about was "The RC is slower
because of debugging?". No. Then the next question that pops into my
mind is "The ports are slow because the binaries are compiled with the
wrong options?". 

Thanks for your clarifications.
