Just saw this shot benchmark on Phoronix dot com today:
http://www.phoronix.com/scan.php?page=news_item&px=MTAyNzA
It may be worth to discuss the sad performance of FBSD in some parts of
the benchmark. A difference of a factor 10 or 100 is simply far beyond
disapointing, it is more than inacceptable and by just reading those
benchmarks, I'd like to drop thinking of using FreeBSD even as a backend
server in scientific and business environments. In detail, some of the
SciMark benches look disappointing.
Why SciMark?
SciMark FreeBSD : Oracle, Mflops
Composite 884.79 : 844.03 (Faster: FreeBSD)
FFT 236.17 : 213.65 (Faster: FreeBSD)
Jacobi 970.76 : 974.84 (Faster: Oracle)
Monte Carlo 443.00 : 246.27 (Faster: FreeBSD)
Sparse Matrix 1213.64 : 1228.22 (Faster: Oracle)
Dense LU 1560.39 : 1557.18 (Faster: FreeBSD)
The threaded I/O results (Oracle outperforms FreeBSD by x10 on one, by
x100 on another test)
or the disc TPS ( 486 : 3526 ) sure look worse and are worth looking into.
Anyway these tests were performed on different hardware, FWIW.
And with different filesystems, different compilers, different GUIs...

Michael
