Experience – what worked and more importantly what didn’t work & gotchas
- For tables less than 50 elements or so, binary search will give more performance than hash tables
- Collision and how to handle collisions is an important factor in designing around hash tables
- There are schemes that generate a perfect hash function, given a set of elements
- While there is no clear size, from my experience, 16 bit hashes that give 65536 elements is a good start
- You can have global and local hash tables ie smaller hash tables than a big hash tables that contains all the elements
