BigIP F5 LTM TCP Profile for High Bandwidth

The default TCP profiles are perfect in most cases such as websites. The default TCP window size is very conservative, and doesn’t work well when downloading large files. The profile example below is designed to enable high speed downloads, however it should be noted that using this profile may result in higher memory utilization, ultimately limiting the total number of connections the F5 can handle at any given time.

There are two profiles that should be applied to the virtual server; a LAN profile and a WAN profile
