Slow transfer speed from DNS323 to Com

Hi, recently facing this issue of slow transfer rate that i have in my LAN. The transfer speed that i sometime face are like 4 - 6MB/s.

The router that i'm using is DIR 655(dlink product). The harddisk that i use for the DNS323 are 1TB  Western Digital Green.

This is the ifconfig from DNS323

egiga0    Link encap:Ethernet  HWaddr XX:XX:XX:XX:48:XX
          inet addr:192.168.0.199  Bcast:192.168.0.255  Mask:255.255.255.0

Re: Slow transfer speed from DNS323 to Com

Are you wired or wireless?  I have the same setup as you, DIR-655 (also have the DIR-685, but just took it out to put in my 655), DNS323 but I have 640GB WD Greens.

Wired (ENABLE JUMBO FRAMES IF YOU CAN, MTU9000), my max is about 22MB/s, lowest I've seen is about 9MB/s.  Wireless is a different story.  Tops about 5MB/s, typically 3.5MB/s though.  I run OSX Snow Leopard with Macbook Pros.

Hope that helps

You need to enable jumbo frames also on your Win7 PC. And the router has to be able to support them.
The speed of 8MB/s is typical for transfers without jumbo frames.

From Google Search:

I have a DLink DIR-655 router also. I contacted support before I purchased it and they informed me that it does NOT support Jumbo Frames.

Re: Slow transfer speed from DNS323 to Com

Thx skydreamer!! Was looking through at another forum and was curious that if a gigabit/jumbo frame support switch was use to transfer between Win 7 and DNS 323, does it help in the transfer speed?

Definitely. I have the same setup myself and the transfer speeds are above 20MB/s.

Thx skydreamer, think i'm gonna get 1 switch soon. Anw does the WD green eco hdd affect the transfer speed aswhile?

Anw dlink support team email me back and told me the following
"
Dear Mr Kevin Lee


   DIR-655 had default hardware built-in and implemented Jumbo frame feature which support size with 9K

Have both the 655 and the 685 and can confirm faster speeds with the 685 hands down.
