# streamex-benchmark
Clojure wrapper over Java streams using StreamEx (https://github.com/amaembo/streamex)
## Usage
From `clj-stream.core-test`:
```clojure
(deftest tests
(is (= (bench
"Clojure seqs:"
(->> (range 1000000)
(filter even?)
(map #(Math/sqrt %))
(reduce +)))
(bench
"Clojure transducers:"
(transduce (comp (filter even?)
(map #(Math/sqrt %)))
+
(range 1000000)))
(bench
"StreamEx streams:"
(-> (range 1000000)
(s/filter even?)
(s/map #(Math/sqrt %))
(s/reduce +))))))
```
Running `lein test` shows:
```
Clojure seqs:
"Elapsed time: 6151.199012 msecs"
Clojure transducers:
"Elapsed time: 3928.352095 msecs"
StreamEx streams:
"Elapsed time: 5092.265878 msecs"
```
So... faster than seqs, but slower than transducers. Hmm.
