2–PlanningPerformance TuningPerformance TuningProper configuration maximizes the router’s performance. Knowing the round-tripdelay (distance between the router and iSCSI initiators) and WAN effective datarate (connection type) allows you to tune the router for optimal performance. Thefollowing tables provide TCP Window Size settings for specific WANenvironments. The TCP Window Size is configured as two parameters: WindowSize and Scaling Factor. See the iSR6200 Router Manager User’s Guide and theiSR6200 CLI User’s Guide for configuring the TCP window size.Table 2-1.
