If you really want speed, you'll need to drop to Java arrays. Overall, your approach is based on a map from cup value (a long) to next cup value (a long). Clojure maps are great for many things, but if you need a fast representation of a mapping from integer to integer, the best option is a Java array. For me, switching from a map-based implementation to an array-based one reduced the time it take for part 2 from ~48s to ~4s.
