Jumbo Frames on TS-109 and TS-209 in gigabit environments

04/09/2007 – 21:23

If using the Qnap NAS systems with a gigabit switch supporting jumbo frames you will obtain around 15-16MB/sec. By activating jumbo frames on the NAS & your network card you can achieve the specified maximum of 32MB/sec download fromthe NAS.

Qnap says the following in the manual:

1) Activating jumbo frames in your network card
In Microsoft Windows, right-click the Network Adapter in Network Connections, and then click Properties.
Click the Configure button and then the General tab. Jumbo MTU is set at 1500 bytes by default. I suggest using 9000 and reducing the value in case of problems.

2) Activating jumbo frames in the NAS
Open the NAs web interface, go to TCP/IP properties, activate jumbo frames with a frame size of 9000 and apply.


3) Optional: Activating jumbo frames in the switch
Most switches in home environments use 9kb frames as a standard. However you can go higher sometimes, especially with managed switches:

  3. No, never used a mac. But look into the network card settings, there should be something similar.

  4. My on-board ‘card’ driver does not appear have this feature so assume this board is too old.
