+#DSL Servlet Benchmarking Test
+
+This servlet uses precompiled DSL model for endpoint communication.
+
+### DSL model
+Data structure is defined in an DSL schema
+
+* [DSL source](src/main/java/dsl/model.dsl)
+
+### JSON Encoding Test
+DSL client Java is used for JSON encoding.
+
+* [JSON test source](src/main/java/dsl/JsonServlet.java)
+
+## Infrastructure Software Versions
+The tests were run with:
+
+* [Oracle Java 1.7](https://www.oracle.com/java/)
+* [Resin 4.0](http://www.caucho.com/)
+* [DSL client Java 1.3](http://github.com/ngs-doo/dsl-client-java)
+
+## Test URLs
+### JSON Encoding Test
+
+http://localhost:8080/servlet-dsl/json
+
+### Plaintext Test
+
+http://localhost:8080/servlet-dsl/plaintext
