freebsd stable - Dec 2011 - Benchmark (Phoronix): FreeBSD 9.0-RC2 vs. Oracle Linux 6.1 Server

Hi,

while the discussion continued here, some work started at some other place.
Now... in case someone here is willing to help instead of talking, feel free to
go to http://wiki.freebsd.org/BenchmarkAdvice and have a look what can be
improved. The page is far from perfect and needs some additional people which
are willing to improve it.

This is only part of the problem. A tuning page in the wiki - which could be
referenced from the benchmark page - would be great too. Any volunteers? A first
step would be to take he tuning-man-page and wikify it. Other tuning sources are
welcome too.

Every FreeBSD dev with a wiki account can hand out write access to the wiki. The
benchmark page gives contributor-access. If someone wants write access create a
FirstnameLastname account and ask here for contributor-access.

Don't worry if you think your english is not good enough, even some one-word
notes can help (and _my_ english got already corrected by other people on the
benchmark page).

Bye,
Alexander.

Unfortunately, M. Larabel is the only one who's performing benchmarks on
FreeBSD, comparing its performance to the Linux-opponents. Adn indeed,
there is a lot of criticism, but no alternative.
I said unfortunately - not offensive - since Larabel and Phoronix are
sadly the only ones who do actually such bechmarking.

It would be much more nicer and kind to support those people.

Well, in January/February we get new hardware. One box is supposed to do
number crunching via 12 cores and a TESLA GPU. My colleague is
developing a high parallelized peice of software for satellite data
transformation. The software package is CPU bound, partially GPU, but
massively memory hungry (96 to 128 GB RAM is needed).
What I can offer is, since I will also work on that machine and I've
free hand to administer, in the spare time of doing my PhD, installing
FreeBSD 9.0/10.0 besides SuSe Linux and looking forward having one ZFS
data storage drive for homes, so both systems can perform on a most
recent ZFS. I'm new to Linux, not a BSD guru, nor I'm a professional
programmer/developer. My skills are sufficient for the daily scientific
work. So, without pressure, I'm willing to perform some HPC benchmarks
under advice if the day comes and those interested in bare numbers of
FreeBSD vs. Linux performance with a real-world-scientific application.

I would appreciate to see some of the developers and/or FreeBSD hackers
to help Phoronix setting up a proper testenvironment instead of bashing
M. Larabel and his fellows.

Regards,
Oliver

Nice to see movement ;-)

But there seems something unclear:

man make.conf(5) says, that  MALLOC_PRODUCTION is a knob set in
/etc/make.conf.
The WiJi says, MALLOC_PRODUCTION is to be set in /etc/src.conf.

What's right and what's wrong now?

Why should you have to tune anything ? Did you tune the Oracle Server
install ? If not, you should not have to tune the FreeBSD install,
that wouldn't be fair. If you tune FreeBSD, you should tune the Oracle
Server install too. It is pretty easy to win at least 30% in
performance for certain workload by choosing the right kernel
configuration.
