Similar to other Layer-7 optimization modules, the HTTP optimization module expects the latency between the server and the server-side SteelHead to be LAN latency. With internet-bound traffic, the latency between the server-side SteelHead and the server is going to be far greater than typical LAN latency. In this case, the URL learning and parse-and-prefetch features are not very effective, and in certain cases they are slower than without optimization. we recommend that you do not disable HTTP automatic configuration—the SteelHead adjusts as necessary. > From SteelHead Deployment Guide - Protocols
