I'd try with real data, not /dev/zero. e.g: dd_rescue -b 1M -m 1.4G /dev/sda testfile.img ... or use whatever non-zero data source you have. dd_rescue will give a nice progress bar and speed indicator. Also, run "iostat -mx 3" while you're running dd, and while accessing it from samba. In my experice, btrfs is simply slower than ext4. Period. There's no way around it for now. -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
