Currently a map with more than 8 elements will be converted from a PersistentArrayMap to a PersistentHashMap, but if using assoc, it will take 9 elements before the conversion happens:
user=> (class {0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7}) clojure.lang.PersistentArrayMap user=> (class {0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8}) clojure.lang.PersistentHashMap user=> (class (assoc {0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7} 8 8)) clojure.lang.PersistentArrayMap user=> (class (assoc {0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7} 8 8 9 9)) clojure.lang.PersistentHashMapAfter patch:
