Hmmm, the machine had a Solars x.y installed a 7 days ago and got a clean
Debian Woody install after an fdisk and formating the partitions with ext3fs.
Thus fragmentation is no argument at all - ext3fs might come to mind as
probable show stopper for this single test ...

On my machine a (not yet used Apache) and a Zope based Content Management
System (ZMS) which is the primary work of the box.  No X11, no database servers
or other stuff is running.
