Problem this snippet solves:

This is a custom TCP profile which optimizes TCP traffic for a Wide Area Network environment by tuning the TCP stack. Enabling selective ACKs produces faster recovery from transmission errors. Nagle's Algorithm reduces the number of short segments on the network. (Enabling this setting for interactive protocols such as telnet may cause degradation on high-latency networks.) The buffer and window sizes are increased to maximize throughput for high-latency conditions.

(This profile is included as a standard profile in LTM 9.4.)

Code :

profile tcp tcp-wan-optimized {
   defaults from tcp
   selective acks enable
   nagle enable
   proxy buffer low 131072
   proxy buffer high 131072
   send buffer 65535
   recv window 65535
