Assign weights based on the log10 of the server's capacity. A server with 10Gbps capacity doesn't necessarily handle 10x more "complexity" than a 1Gbps server; using a log scale helps find the "sweet spot" for performance.
If you are an architect looking to move beyond simple weighted distribution, consider these steps: log10 loadshare
At its core, log10 loadshare refers to a method of . Assign weights based on the log10 of the server's capacity
