disk storage blocks when a file is extended to the Windows behaviour
of actually forcing the disk system to allocate real storage blocks
when a file is created or extended to be a given size. In UNIX
terminology this means that Samba will stop creating sparse files.
This can be slow on some systems. When you work with large files like
>100MB or so you may even run into problems with clients running into
timeouts.</para>

<para>This option is really desgined for file systems that support
fast allocation of large numbers of blocks such as extent-based file systems.
On file systems that don't support extents (most notably ext3) this can
make Samba slower. When you work with large files over >100MB on file
systems without extents you may even run into problems with clients
running into timeouts.</para>
<para>When you have an extent based filesystem it's likely that we can make
use of unwritten extents which allows Samba to allocate even large amounts
