LAN<>LAN speed 12MB/s from DIR-655 to DNS-323
« on: January 02, 2009, 11:55:01 PM »
I bought a new DIR-655 today but I get only a 11 MB/s network speed when copying ripped DVD's from my PC to my DIR-323 NAS over a DIR-655.

This is the configuration

  • Gigabyte GA-E7AUM-DS2H (NVIDIA GeForce 9400 chipset, Realtek 8211CL chip (10/100/1000 Mbit), Vista SP1)
  • DIR-655 (firmware 1.21EU, Rev A2)
  • DNS-323 NAS (firmware 1.06)

The cables are CAT6 and 3 mtr.

Any suggestions.

Sharepoint is by the way great, works perfect on wireless and non-wireless, Vista (only had to do a fresh re-install) and XP

what antivirus do you use?
try turning it off while copying
and use drivers for your NIC from your mainboard manufactorer
i had around 12 MB/s (100mbit) with a Cnet gigabit switch to
when i did what i said above my speed jumped to 30 MB/s+

my setup
Vista SP1 64-bit
NOD32 Antivirus 3.0
two PCs with Gigabit Realtek PCIe chips built into MBs
CNet Gigabit Switch
D-Link DIR-655
Speedtouch ADSL+ Router

Already resolved it on another forum. DNS-232 Gigabit LAN maxes out close to 15 Mb/s, so his throughput is not far off.

Got the measurements from a highly reputated tech site doing tests with the DNS-323.

IOZone Write - Gigabit LAN (kByte/s) 11407
IOZone ReWrite - Gigabit LAN (kByte/s) 24502
IOZone Read - Gigabit LAN (kByte/s) 15500
IOZone ReRead - Gigabit LAN (kByte/s) 15537


Did not produce them myself

I had this issue and is now resolved...
1) Reset to factory defaults DIR-655
2) Reset DNS-323 to factory defaults as well
3) done.

This bumped me from 12MB/s to 24MB/s copying 800MB file in less than 30secs from my PC on second floor, wired down to basement, patche to DIR-655 in living room (approximately 100ft of CAT6 cabling). Jumbo frames doesnt help in small LAN's (got that from the God Mod's). Of course the DIR-655 handles up to 4000k jumbo frames...so if you want to prevent switching...set all to 4000k frames. Anything above is useless. In fact Jumbos are usless for small LAN's but if it makes you feel better set it up. In my experience I haven't noticed any improvements. If you are testing test several times to get an idea of what average throughput.

MOBO: Gigabyte--

Cheers!
