This integer, from 1 to 100, is the weight given to a site's current load when the WSD makes a proximity-based dispatching decision. An admin tunes it relative to the hops and latency weights to prevent an otherwise nearby site from being overloaded, directing more traffic to a less busy site instead. Setting it well above the default of 50 during a traffic spike would bias dispatch decisions toward the least-loaded site rather than the nearest one.
