  "message": "Upstream hash: speedup consistent hash init.\n\nRepeatedly calling ngx_http_upstream_add_chash_point() to create\nthe points array in sorted order, is O(n^2) to the total weight.\nThis can cause nginx startup and reconfigure to be substantially\ndelayed.  For example, when total weight is 1000, startup takes\n5s on a modern laptop.\n\nReplace this with a linear insertion followed by QuickSort and\nduplicates removal.  Startup for total weight of 1000 reduces to 40ms.\n\nBased on a patch by Wai Keen Woon.\n",
