 ## Performance
 
-SD is designed to be extremely efficient in order to support a very large number of flash cards and should be able to handle several billion cards with ease. If `N` is the number of cards, initializing the program requires `O(N)` time and `O(N)` memory. Selecting a random card and adjusting its weight based on if the user got it correct requires `O(log N)` time. Internally SD uses [segment trees](https://en.wikipedia.org/wiki/Segment_tree) to achieve this time complexity.

 A C port for maximal speed and minimal executable size is planned but will probably never happen.
