Post some links of these "qualified people" that are concerning
themselves with fragmentation. I'd love to learn why they stand out
from everyone I've ever read discussing this non-issue.

Search for Fragmentation and Linux and you will find a number of
reputable, large, Linux foundation websites, directly dedicated to the
Linux community, where it is properly talked about and the impact it
can and does have.

OK, last kick at this cat. You wanted me to search for a "reputable"
Linux website. I guess there isn't one more reputable than linux.org,
which has been servicing the Linux community since 1994. Here's what its
docs section has to say on this subject:

" Noncontiguous placement of blocks in a file is bad for performance,
since files are often accessed in a sequential manner. It forces the
operating system to split a disk access and the disk to move the head.
This is called "external fragmentation" or simply "fragmentation" and is
a common problem with MS-DOS file systems. In conjunction with the
abysmal buffer cache used by MS-DOS, the effects of file fragmentation on
performance are very noticeable. DOS users are accustomed to defragging
their disks every few weeks and some have even developed some ritualistic
beliefs regarding defragmentation.

None of these habits should be carried over to Linux and ext2. Linux
native file systems do not need defragmentation under normal use and this
includes any condition with at least 5% of free space on a disk. "

I admit that it does not explain why file fragmentation is a non-issue on
a Linux system, but I've posted other links in this thread that does
explain why this is so in detail and why on Linux file fragmentation can
be considered a positive thing. Specifically one should look at the
postings by Linux experts such as Lew Pitcher and Peter T Breuer on
Usenet, who get into the nitty gritty about the technical end of how
Linux deals with external fragmentation.

http://www.linuxquestions.org/questions/showthread.php?t=93224

If you had read other linux site, including the one you quoted, you
would find that there ARE times when fragmentation does impact users,
and in the case of this group, most users are single user solutions and
not servers.

The only poster in that thread that claims defragging "might" be necessary
is Dark Helmet and he's wrong. In fact, if you read his post he's not too
sure if daemons can be considered users. Well, Linux is not only a
multiuser system, but also multitasker and multithreaded. Files are
CONSTANTLY being written to the hard drive even if just a single user is
logged in. Just run a "tail -f" on some of the /var/log files and you'll
quickly see what I'm talking about. Constant file writing isn't only
confined to log files either. The whole system is based on a server/client
model and much activity is constantly going on in the background and dot
files are constantly being updated and rewritten.

Had you bothered to read Lew Pitcher posting, you would end this silliness
by now and recognize that fragmented files under Linux IS NOT an issue.
But, enuf said ... it's obvious that you just aren't prepared to take no
(defragging is necessary) for an answer.

BTW, I'm still waiting for you to post links to the "experts" you claim
suggest otherwise and that is so readily available.
