The fragmentation on NTFS was a problem even when nothing else was running
on the server. The preallocation patch made all the difference on NTFS and
cygwin. In that world it is a must have since it increases performance on
the reads by orders of magnitude while not impacting the write-side since
the cygwin posix_fallocate is very efficient.
