Testing a N5200 (Raid5, WD500YS, directly attached to PC) with Iometer (Read/Write 50/50 Random/Sequential 50/50 96KB Size) (www.iometer.org) I´ve got an average 8 MB/sec overall performance.
This does not fit to all the reports and test which mention a performance up to 35-40 MB/sec.
Could anybody do some testing as well and post the results in the forum?

Connected via 100Mbps or 1000Mbps on the PC?
Accounting for TCP/IP overhead, that is about on par with a 100Mbps network connection. If you are connected with a 10/100Mbps NIC, that seems about right.
Its slow for a gigE connection though (1000Mbps).
That said, I personally get about 12-15Mbps using a 1000Mbps connection with 9K jumbo frames which actually seems somewhat slow (though tolerable) to me.

You said connected directly... I assume that means a crossover cable?
Make sure that it is cat5e or cat6. Regular cat5 isn't good for gigE.
If you are going through a switch, make sure you are linking at 1000Mbps.
Also benchmark your local PC hard disk.

There is no need for a crosover cable. Just a normal patch cable is recognized like in most of the other NAS products (Terastation e.g.).
As far as the type of cable does not make a difference concernig the capacity were talking about, I tried the same with correctly configured HP Gigabitswitch and Netgear as well. No differences in performance. Jumbo frames even worse the results.

Well... regular cat5 may let you link at 1000Mbps, but its generally not rated for sustained gigE speeds.
If your Cat5 has 8 wires (4 pair), it *MAY* support gigabit speeds. If you opted for less expensive Cat5 cabling that only has 4 wires, you’ll definitely need a new cable. To play it safe, I'd make sure you try it with actual cat5e or cat6 cables.
Also, old, kinked, or cheap cables can cause problems. Cables DO matter. Some cables can also seem to negotiate at 1000Mbps but not actually transfer at those rates.
Make sure all link lights are showing 1000Mbps.
Make sure your PC is showing the connection at 1000Mbps under the 'Local Area Connection Status'.
Make sure you are running the latest drivers for your NIC.
Make sure you are running in Full Duplex.
What sorts of speeds do you get when using FTP, SMB, NFS, HTTP instead of Iometer?
Have you tried using static IPs on both your NAS and PC?

I can only confirm that my performance experience with TheCus N5200 is very good. FTP Transfers clock in around 38-40MB/s between the N5200 and my Powermac G5 connected via a Gigabitethernet DLINK Switch.
My problem with N5200 is not performance but stability. N5200 reboots itself every 24-48 hours and the LCD freezes. :-(
And yes.. I even tried the last beta firmware 1.00.04.9

I even tried the last beta firmware 1.00.04.9 I only had problems similar to this when I had 100% full snapshots... though since snapshots were disabled in the latest beta firmware, you may have a different issue. Anything useful in the logs? Any disks with numerous SMART errors? Does it do it on its own, or usually during a transfer? |

FTP Transfers clock in around 38-40MB/s between the N5200 and my Powermac G5 connected via a Gigabitethernet DLINK Switch. Unfortunately I can not confirm this performance. I tried another test with DTR2000 (http://www.mksoft.nu/dtr/dtr2000_1.20.zip) and achieved a maximum of 12 MB/sec. Your reboot issue never made any problems on my N5200. Concerning all the problems in this forum, the box seems to be a bit unstable running linux - never had any of this problems on my old terastation. Maybe Thecus should give W2K3 storageserver a try ;-) |
