Help text

The maglev hashing scheduler maps source IPs to destinations stored in a hash table. This table is assigned by a preference list of the positions to each destination until all slots in the table are filled. The index determines the prime for size of the table as 251, 509, 1021, 2039, 4093, 8191, 16381, 32749, 65521 or 131071. When using weights to allow destinations to receive more connections, the table is assigned an amount proportional to the weights specified. The table needs to be large enough to effectively fit all the destinations multiplied by their respective weights.
