Dynamic evaluation and adaption of hardware hash function

A computer program product for creating hash values based on bit values of an input vector, the computer program product comprising

• a non-transitory computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• configuring a first hash function for creation of a first hash value based on the bit values of the input vector, the first hash value to be stored in a first hash table;
• configuring a second hash function for creation of a second hash value based on the bit values of the input vector, the second hash value to be stored in a second hash table, the second hash table having fewer entries than the first hash table;
• comparing an effectiveness of the first hash function with an effectiveness of the second hash function;
• and
• based on the comparing, replacing the first hash function with the second hash function.
