+In order to test sync produce the performance I've prepared a benchmark that uses [benchee](https://github.com/bencheeorg/benchee) to produce
 kafka records on kafka cluster running locally on my machine.
 
 The details can be checked out on `benchmark.ex` mix task and the results on `bechmark_results`.

 With this scenario I've executed the benchmark increasing the `parallel` attribute from
 benchee from 1 to 16, doubling it each round. The results are the following:

+### Produce async
+
+The asynchronous benchmark spawns N parallel processes producing to one of 3 topics in a loop. After 10 seconds,
+it calculates the difference between the initial and current offsets for each topic partition to determine
+the total records produced and the throughput (records per second).
+
+The details can be checked out on `async_producer_benchmark.ex`.
+
+To reproduce it on your setup you can run (16 is the N value):
+
+```
+bash start-kafka.sh
+mix benchmark producer_async 16
+```
