+h1. Hash vs Hazelcast vs Infinispan
+
+h2. Overview
+
+This is just a simple benchmark to compare Hazelcast and Infinispan performance (with defaults), and includes a regular Hash object as a baseline.
+
+h2. Usage
+
+From the root of the project run:
+
+bc. mvn clean install
+
+Then you can just start it up:
+
+bc. java -jar target/map-benchmarks-1.0.0.jar
+
+h2. Results:
+
+On a Core 2 Duo laptop running at 2.66GHz these are my results:
