PRO 6 poor read performance??

When I said PC, I was referring to your Windows machine not the NAS. How many and what disks are in your Windows machine? Are you using RAID in your Windows machine?

Oops, sorry I misread it. The T410 is a laptop, it has a single 500 GB hard drive (7200 rpm, but only 60 MB/s). So I can only get useful numbers for it with IOmeter, since if I copy information to the drive, I will be limited by it. I have some esata drives that are faster, but haven't had a chance to plug them in. The Vista machine does not have raid. The C drive is a performance WD 1 TB (forget the exact model), there is also a 2 TB WD and a 1 TB Seagate. All run in excess of 100 MB/s. I also have an XP desktop with 3-4 fast drives, but haven't tried that one for benchmarking. (Also doesn't run raid).

FYI my PC was an i3-540 on a Gigabyte M-ITX mobo using an Intel SSD. I had much the same I/O results using the mobo NIC - Realtek RTL8111E. Have you tried changing the Flow Control settings ? I changed them to be active. I also remember that there were problems with the settings on the switches. You might also install NetMeter on the PC and have a look at the trace of the data transfers. I found that there was a lot of up/down traffic that caused stop/start behaviour. It's here : http://www.metal-machine.de/readerror/i ... ;dl=item23

thx for the pointer on Netmeter. Flow control is on in the NIC cards (and also is enabled in the GS108Tv2). The Vista machine has RealTek RTL8168C(P)/8111C(P), the T410 has an Intel 82577LM. IF anyone has suggesting settings for either, that would be useful.

BTW, I get much faster IOmeter readings if I change the number of outstanding transactions from 1 to something higher. So there may be a clue there.
