While that almost certainly constitutes "significant fragmentation"
it probably has very little effect on performance. It _would_
affect performance if that file were being read sequentially, but
ELF binaries don't get loaded that way. Individual pages are
read in via demand paging, and the next page needed could be from
anywhere in the file.
I thought we were discussing ext3 and what could happen with it.
Someone was claiming that ext3 was inherently immune or
nearly so to fragmentation.
So, back to the OP's question: Where is there/why isn't there
a defragmenter for ext3?
With a file system that typically minimizes fragmentation and an
OS that isn't very sensitive to such fragmentation as is likely
to occur, there is just insufficient perceived need to justify
the effort for writing one.
