How can I optimize hash table performance in C++?

How can I optimize hash table performance in C++?

To optimize hash table performance in C++, consider using a good hash function, minimizing collisions, and resizing the table appropriately.

What are some good hash functions I can use?

Some good hash functions include MurmurHash, CityHash, and FNV-1a. They provide a good balance between speed and distribution.

How do I handle collisions effectively?

You can handle collisions using methods like chaining, open addressing, or double hashing. Each has its pros and cons.

When should I resize my hash table?

You should resize your hash table when the load factor exceeds a certain threshold, typically around 0.7 to 0.75.
