Many are below 4K and lots are below 1K. How does this compare with what's on the rest of /usr/share or even /usr? I have a "Media" folder - are the movies worth putting on a XFS?
No.
The pictures?
No.
What about raw downloads from my camera?
No.
Yes, things like ReiserFS and EXT seem very resilient as "general purpose", but could I optimise the 'static' things like those icons? Only a few hundred meg? Is it worth it? Probably not.
Correct.
But then what about the movies I download from my camera? My photo galleries?
No.
I'm looking at experimenting with other file systems like btrfs, xfs and the like to see how they perform with various fixes of files - videos, icons, mail boxes, PDFs, development (source and object fragments) Perhaps you could post the results here? I'm certain quite a few would be interested. I'd be happy to, but don't expect the same level of detail as you'll find at www.phoronix.com. I you want solid numbers look at their test suite http://www.phoronix-test-suite.com/ and results http://www.phoronix.com/scan.php?page=article&item=linux2635_btrfs&num=1 I was asking about, the paper I referred to in my original post was talking abut, distribution of file sizes. The paper discussed block size and file fragmentation. With modern file systems that can 'stuff' more than one file in logical extent (?block?) the fragmentation isn't so much an issue, but file system coherency, especially after many deletes/edits, is another matter. Still, if I have my "media" FS, should I use XFS? Should I have a different file system for /use/share/icons where the SVGs are mainly under 64K (many even under 1K) and optimise it for those smaller files? What would be the best file system type for my backing databases - MySQL, SQLite and the simple SleepyCat Berkeley DB (so what do YOU use for LDAP, then?)
I use ext3 for OpenLDAP. With modern systems there isn't really any point in using anything else [we used to be a primarily XFS shop]. At least not until btrfs arrives. Any [negligable] gain is easily negated by the added complexity of your setup. -- Adam Tauno Williams <awilliam@whitemice.org> LPIC-1, Novell CLA <http://www.whitemiceconsulting.com> OpenGroupware, Cyrus IMAPd, Postfix, OpenLDAP, Samba -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
