FreeBSD 8.0 Performance (at Phoronix)

HI,

Phoronix recently published a comparative benchmark[1] for FreeBSD 7.2/8.0 
against Linux and OpenSolaris.  I would like to bring some of the good and bad 
to light (in the hopes that the developers with the correct expertise will be 
intrigued).  

The tests were performed with a 'standard' installation of FreeBSD on a Lenovo 
ThinkPad T61.  

I've tried to eliminate tests who's performance is a result of compiler 
differences and/or 3rd party applications and tests who's statistical 
significance are not so strong (subjective guess).  

Improvements for FreeBSD 8.0 vs 7.2:
 - 7-Zip Compression (page 3)
 - Timed MAFFT Alignment (page 5)
 - GraphicsMagick (page 5)
 - Threaded IO (64MB Random Write - 32 threads) (page 7)
 - Threaded IO (64MB Read - 32 threads) (page 7)

Regressions for FreeBSD 8.0 vs 7.2:
 - Gzip compressions of a 2GB file (page 3)
 - C-Ray (page 4)
 - Threaded IO (64MB Write - 4 threads) (page 7)
 - Threaded IO (64MB Write - 32 threads) (page 7)

Poor performance relative to Linux and OpenSolaris
 - Threaded IO (especially random writes) (page 7)
 - OpenSSL (RSA 4096bit) (page 8)
 - PostMark (disk transaction) (page 8)

It appears that threaded activity on UFS does not fair well against Linux/ext4 
and OpenSolaris/ZFS.  Phoronix intends to do a comparative test against 
FreeBSD and OpenSolaris on ZFS. 

Regards,

David
