Running the vpn build of V24-K26/svn17084 on a WRT610N. I just bought a D-Link DNS-320 NAS. It has a gigabit adapter, as does my desktop PC (D-Link DGE-530T). I've been transferring several hundred gigs of data to the DNS-320 and I'm clearly not not getting gigabit throughput. Just doing copy/paste to the CIFS share from my Windows 7 box to the DNS-320 and Windows reports a pretty consistent 12 MB/s transfer rate. I calculate that to be right around 96 Mb/s, just about perfect for fast ethernet. I'm sure this DNS-320 or even my own desktop will never get "full" gigabit throughput, but I assumed I would get a whole lot better than this. I don't have another gigabit switch to test with right now, but I thought about buying a 4 port gig switch to see if I get different rates through another switch. But first I thought I'd ask if there's something I can do/check on DD-WRT. The DNS-320 and my PC are both definitely auto negotiating at 1000/full. The WRT610N LEDs light up green for gigabit, as opposed to blue for 10/100. Any suggestions?

There is more to Gigabit speeds than just router/switch support. Cabling should be Cat 6 (some Cat 5e may work at Gigabit but depends on the quality of the cable). Devices must have a Gigabit Ethernet port.
I have a Syology NAS Array with 4 Green Drives in Raid 5 configuration that has a Gigabit Ethernet port and I peak around 150-200Mbps on file transfers. The limitation can be the on-board processor and/or drives. But my configuration to have low energy use and low heat was my 1st priority over speed, so I'm very happy with it.
Other way to test your Gigabit ports is to get a CAT 6 Cross-Over Cable and connect your PC directly to your NAS. You will need to set static addresses on your NAS and PC. _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone

I visit a number of forums and this speed thing always comes up.
I'm not saying this is the OP, but soooo many people figure that when a 1Gb/s connection is negotiated, then the transfer rate should be 1Gb/s or very close to it.
It just won't happen.
I've taken a couple of Intel hexacore MBs using PCIe Intel server NICs with onboard processors, a direct connection between the two and only achieved about 950-960 Mb/s.
Some of these SoC devices won't achieve 100Mb/s transfer rates with a negotiated 1Gb/s connection.
While I'm yanging. Lets look at hard drives. Most of the new drives offer SATA 3. A connection rate of 6Gb/s. Nice, say what?
The issue being, no current 7200RPM hard drive can even fill a SATA 2 3Gb/s connection. I's all smoke and mirrors.
SATA 3 (6Gb/s) was designed for SSD and maybe some day SSD might achieve 6Gb/s.
