Laut deinem Link:
-----------------
The most efficient way to allocate file system blocks when data is to be
written into all of the file (for example, a streaming video write) is
to allocate what is called an "extent" on the file system. The requested
blocks are then laid out by the underlying file system (ext4 or XFS) in
a very efficient way which causes the actual writes to be much faster
than having to allocate them dynamically.


Und nach der smb.conf.5
-------------------
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.


Wenn man das Zusammenwürfelt passt meine Beobachtung die ich mit einem
Notebook und ext3 (ohne Raid) gemacht habe, dabei war es das gleiche
Problem wie bei Frank Meyer.
