Fair enough.

I didn't imply that it was. However, reinstalling Cygwin would probably
defragment the Cygwin DLLs and not much else. :-)

True. However, interactions of Cygwin with other programs are related to
Cygwin, and the Cygwin setup procedure is such that it is more likely to
produce many fragmented files over time (since Cygwin is updated more
often than most other commonly used programs). FWIW, it may well be more
than just defragmentation -- I suspect disk locality also played a role.
But, as you said, until someone tests it, it's just a theory.
