+ | CTF uses an alternative forwarding method to Store and Forward in bridges. You may need this option if you are on an Internet plan/tier that offers speeds above 100 Mb /second. You may not experience speed differences at this speed. However, CTF is usually necessary to achieve peak speeds at 200 Megabits/ | ||
+ | |||
+ | With CTF enabled, the router starts to send out transmission frames as soon as it receives its destination. However, the router relies on the client device to tell it whether the data is corrupted for resend. This restriction can cause problems with a few common home uses. Note that enabling CTF will disable QoS and Bandwidth Limiter. This is because the switching part of the packet bypasses parts of the standard Linux iptable chains. | ||
+ | |||
+ | When you have CTF disabled, the router will store the entire frame before sending it out to its destination. When this happens: | ||

+ | * WAN-to-LAN performance depends more on the router model in use. | ||
+ | * For example, CTF could allow you to use your FreshTomato device in a Gigabit WAN environment. On ARM devices, you can expect performance in the range of 200 to 400 Mb/s. | ||
