With these changes, encode & decode is about 4 times faster.

I testes this code using criterium.

(use 'criterium.core)
(require '[clojure-erlastic.core :as c])

(def conf {:str-detect :none :convention :elixir :str-autodetect-len 10})

(def encode #(c/encode % conf))
(def decode #(c/decode % conf))

(defn f
  []
  (-> :toto encode decode)
  (-> {:a :b :c :d} encode decode)
  (-> [:a :b :c :d] encode decode)
  (-> '(:a :b :c :d) encode decode)
  (-> #{:a :b :c :d} encode decode)
  (-> 4.3 encode decode)
  (-> true encode decode)
  (-> (byte-array (repeat 4 0)) encode decode)
  (-> nil encode decode)
  (-> \c encode decode)
  (-> "toto" encode decode)
  nil)
(bench (f))
