... This creates a lot of disk seeks when traversing the
directory trees.  For me it helps to execute "e2fschk -D"
monthly on the backup disk.  It optimises the directory
structure.  I observe a significant decrease in rsnapshot
execution time after each cron run.

In effetti a me dopo aver cancellato la copia di /usr e`
andato forte per una settimana poi ha ri-rallentato...

Ho quindi provato a fare un "defrag" (parola bruttissima nota
in ambiente $AltroOS) e ho beccato un altro problema, la ram:

# /etc/rcK.d/K21smb stop
Shutting down SMB services: smbd nmbd.
Shutting down winbindd services: winbindd.

# /etc/rcK.d/K25nfs stop

Shutting down NFS mountd:  rpc.mountd.
Shutting down NFS quotas:  rpc.rquotad.
Stopping portmap.
