Unfortunately, I am unaware of any performance testing of [collections],
other than of individual classes:
- TreeList is faster than LinkedList, and can for some cases be faster
than an Arraylist
- Flat3Map is faster than a HashMap at size 3 or less
If anyone did any more performance testing, hopefully they can share
their results with the list.
