Chart comparing the busiest node's load for hash rings with different virtual node counts, rendezvous hashing and jump hash

Consistent hashing: 100 virtual nodes still run 18% hot

A hash ring with 100 virtual nodes per server still leaves the busiest of 10 servers about 18% above the average load. In our lab it took 1,000 virtual nodes to bring that down to 5%. Rendezvous

Chart comparing the maximum requests accepted per minute by four rate limiting algorithms against a limit of 100

Rate limiter algorithms compared: the 2x burst most miss

A fixed window limiter and a token bucket limiter can both let a client send nearly double the configured limit inside one minute. In our Redis lab, a "100 requests per minute" rule let 200 requests
