Yeah, it's a start.  I pretty much figured it was going to be the same
story as any other file system.  I push my systems hard.  And I have
lots of small files which doesn't really help.

Now, can anyone tell me if a defragmenter would help for ext3?  Or not? 
It helps a ton with NTFS, but would the same thing happen to a linux fs?
