Are you using the OS X client and experiencing much slower transfer speeds over SMB? This is likely due to an OS X bug related to Badlock, about which you can read more here.
The way to fix it is fairly easy. Check the
/etc folder for a file named
nsmb.conf. If it exists, edit the value for
no. If it doesn't exist, run the following commands:
echo "[default]" >> /etc/nsmb.conf
echo "signing_required=no" >> /etc/nsmb.conf
That's all. Restart the computer, remount the share and SMB speeds should now match those over AFP.
