WebThe problem with linear probing is primary clustering. This means that even if the table is empty, any key that hashes to table requires several attempt to resolve the collision because it has to cross over the blocks of occupied cell. These blocks of occupied cell form the primary clustering.

Because linear probing is especially sensitive to unevenly distributed hash values, it is important to combine it with a high-quality hash function that does not produce such irregularities. The analysis above assumes that each key's hash is a random number independent of the hashes of all the other keys. This assumption is unrealistic for most applications of hashing.
