Actually for file shaing it would need a cluster file system, such as
Stornext and friends... Not exactly easy, nor cheap (unless your
machines are all Linux and can use GFS or OCFS).

Yes, that's why I asked what's the disk performance like on the SMB
server side. If already the server reads/writes slowly, samba won't
speed anything up.

As a side note, Götz, you definitely want write-back on the iSCSI side.
It's terribly unsafe, but that's the only way to get decent performance
from an iSCSI storage backend.
