Constant Time LFU
Caching is a popular way to improve application performance. The LRU strategy is popular, even though it is sometimes sub-optimal compared to the LFU strategy, because it has constant-time performance. However, you can improve LFU to get constant time performance, with some memory overhead as a trade-off.
