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.)
