Jumbo Frame On or Off

Jumbo Frame is used in order to improve data transmission efficiency. There are some router manufacturers that allow you to tweak them like Asus or Cisco. In this article, you will learn how exactly Jumbo Frames actually works. You will also be able to learn how and when to use it. This article is written in very simple words and no technical terms have been used in it. The main objective of writing this article is to make using Jumbo Frame as simple as possible.

Jumbo Frame

It is a very useful feature and after using it you will notice a significant improvement in data transmission. In Jumbo Frame, data frame has 9000MTU unlike 1500MTU in the standard data frame. This is why data transmission efficiency improves radically. There are two ways in which data transmission is improved when Jumbo Frame is enabled. First, each frame sent has regarding those frames. Secondly, there are less interrupted frames when a bigger amount of data is sent. This is how the CPU usage of the access point is improved which results in improved network efficiency under heavy usage of your access point.

This feature is normally recommended when there is a network storage attached to your network. For instance, you use external media library to store large video or image files.

Jumbo Frame Setting

One thing you need to keep in mind is that this feature is not enabled for wireless connections. It is because it only works over Gigabit Ethernet over LAN setting. Remember every single node such as your access point etc needs to support jumbo frame. Make sure that all the nodes have the correct setup otherwise they will have negative effects on the performance of the network.

This is how you can find Jumbo Frame setting:

For router setting, locate jumbo feature under LAN setting.

For switches, first be sure that they support jumbo frame.

You will need to change the networking card setting

Advantages/Disadvantages

Advantages

People use the Jumbo Frame feature because it improves data transmission efficiency. When there are few interrupts of large transferred files, the performance of the access point or router is automatically improved. Generally, routers can achieve twenty to thirty percent improvement in data transmission process.

Disadvantages

When there are large filed involved, we use the Jumbo Frame feature. But thanks to the advanced routers available these days you no more need the Jumbo feature. There are a lot of issues you may have to face in order to make sure that jumbo feature setup is working as it should. It starts creating problems if there is component that does not support Jumbo frame.

The feature should be enabled if there is any internal network storage solution. You better disable the feature if there is any sort of internet access. Following are different scenarios to help you decide whether you should enable or disable the Jumbo frame feature.

For Gaming

When playing a game, you cannot afford to miss even a single click.  This is why the size of files and games is kept minimized. The size of your game traffic will be smaller than the standard MTU size. So enabling Jumbo Frame is not going to improve gaming performance. This is also true for consoles like Xbox.

For Internet Video Streaming

Popular services like Apple TV and Roku don’t support jumbo frame feature. So there is no point using the Jumbo frame feature. Same is the case with VoIP which is also latency and time sensitive.

For Internet Purpose

Enabling the Jumbo feature is not going to benefit you because the Internet does not support Jumbo Frame. Basic Internet use like browsing and email are not going to be affected by Jumbo feature.

To conclude we can say that you better not enable jumbo feature if you are a general home user. You can consider enabling this feature if there is a network storage attached to your network. For instance, you use external media library to store large video or image files.
