Not sure if you are just poking fun at me, but the link above has five
messages in the thread and you need to follow all of them to get all of the
information I received about defragging.
But, to answer your question, I'm not sure that it is really bad (i.e. that
it is hurting performance to a noticeable degree). One of the responses
specifically cautioned against running xfs_fsr on any partition that was
anything other than partially full and that the kernel should be expected to
take care of it.
