Throughput: Harddisk on USB-Port === ar9132 === RTL8366RB === GbE PC
Using Samba I only reach:
22.214.171.1240 Byte = write ext4-Partition => Duration 5:47min=347sec eq 8,6MB/s
126.96.36.1990 Byte = write ntfs-Partition => Duration 25:59min=1559sec eq 1,9MB/s
188.8.131.520 Byte = read ntfs-Partition => Duration 6:20=380sec eq 7,8MB/s
To some this results may seam all right, but to me they are not. Don't know about you guys, but I purposely bought a device with GbE, so that I would have a theoretical maximum bandwith of 125MB/s duplex with the real threshhold being the USB2.0 througput. 40MB/s are reasonable. (3,5" 160GB SATA in USB-Casing, reaches 60MB/s on SATA).
But so far the bottleneck seems to be the CPU (400Mhz!) or samba or simply it's implementation. Maybe the code is not written in a manner that does perform well on MIPS. I don't know. However, as I am not planing to share a printer on the network, I shall try NFS. I am really expecting to exhaust the USB throughput.
BTW: a 1TB Harddisk is capable of a thoughput of ~100MB/s. Whilst USB2 has theoretical maximum of 480MBit/s, my "USB"-Casing features an eSATA Port, too. So with some SATA connectivity one would be able to realize a mighty little NAS solution. Well, in theory...
Who else is interested in getting at least the full throughput of the USB to work?
