+ | * The holding period may require more of the router' | ||
+ | * WAN-to-LAN performance will depend more on the router model in use. | ||
+ | |||
+ | CTF/FastNAT is supported as follows: | ||
+ | |||
+ | * ARM Routers (like the RT-AC68U, RT-AC3200, R7000) support CTF. | ||
+ | |||
+ | * MIPS RT-N routers (like the E4200v1, RT-N16) can use Broadcom FastNAT | ||
+ | * FastNAT is a similar function to forward at accelerated speeds. | ||
+ | * MIPS RT-AC routers (like the RT-AC66U) do not support CTF or FastNAT. | ||
+ | |||
+ | \\ | ||
+ | |||
+ | On ARM-based devices, you can expect performance in the range of 200 to 400 Mb/s with CTF enabled. | ||
+ | |||
+ | \\ **Enable Jumbo Frames * :** This option allows you to increase the maximum frame size within the LAN. (Default: Disabled). | ||
+ | |||
+ | The default size for Jumbo Frames is 2000 bytes. If enabled, all ports (WAN + LAN) will have Jumbo Frame capability enabled. | ||
+ | |||
+ | The jumbo frames feature is only supported in 1000 Mbit/s mode. Also, a gigabit switch uses more memory when this feature is enabled. This will influence system performance, | ||
+ | |||
+ | The asterisk (*) indicates that not all hardware models support this feature. | ||
+ | |||
+ | **Jumbo Frame Size:** If disabled, the default frame size is 2000 bytes. If this is enabled, its setting overrides the default frame size setting (Default: off). | ||
+ | |||
+ | Generally, enable Jumbo Frames only if you frequently transfer large files within your LAN. To function, all devices must support Jumbo Frames. Additionally, | ||
+ | |||
+ | You are strongly advised to leave this disabled unless you have specific requirements for it. Venturing into Jumbo Frames means you'll have to deal with fragmentation of Internet traffic, unless the end device supports Path MTU Discovery. Users often find that the limited performance benefits of Jumbo Frames is not worth the time and effort needed to tune and troubleshoot it. | ||
