Poor streaming connection/speed

Hi,

Thanks again. I can't see anything that could be limiting performance on the PC or network card side of things, though I have just changed the card's speed setting from 'auto-detect' to Gigabit. To be frank, I am not certain what some of the settings are (so I've left them alone).

I have also carried out a direct connection after giving the PC a static IP address... I got 29 Mb/s write and 23.8 Mb/s read. All the testing I have been doing has been with the NAS Performance tester (since you mentioned a few days ago; great tool - thanks!), and with my firewall de-activated. Seems that something is almost halving my speeds - could being 85%full really lead to this much of a performance drop?

Following your suggestions earlier, all Advanced settings other than those below are disabled;

ARP Offload - enabled
Flow Control - enabled
Priority & VLAN - Priority & VLAN enabled
Receive Buffers - 512
Receive Side Scaling - enabled
Shutdown Wake-On-Lan - enabled
Speed & Duplex - 1.0 Gbps Full Duplex (was set on Auto Negotiation)
Transmit Buffers - 128
Wake on Magic Packet - enabled
Wake on pattern match - enabled
WOL & Shutdown Link Speed - 10 Mbps First

If all this looks OK, then I assume that I'm definately looking at the NAS itself as the source of slowdown?
