Specifically not true. "Discussion" and "worry" are two different
things. I am myself not worried about whatever the effects on
performance might be, since I am not experiencing any problems
with disc performance. I have not made any claims that whatever
performance hits there are are significant to me. Whether they
are significant to others depends on a variety of factors. I also
don't argue that *you* experience problems with disc performance.

If you actually read what I wrote, you will see that my statement is
that claims that there is no effect on performance is fertilizer.
I did not claim that the effects, whatever they are, bother me,
or anyone else. I simply state that they *exist*.

It is entirely possible that, on my machine, the fragmentation
*enhances* performance. Unlikely, but possible.
