Specifically, … WebA uniform hash function produces clustering near 1.0 with high probability. A clustering measure of c > 1 greater than one means that the performance of the hash table is slowed down by clustering. For example, if all elements are hashed into one bucket, the clustering measure will be n 2 / n - α = n -α .
