you will need to.... a) get the branch i pushed [1] b) get the artifacts to serve using httpd [2] c) configure you httpd with a volume to serve the artifacts d) install the 5.1-beta dependencies to your local maven repository e) run the Maven package goal f) run the benchmark [3] The field Main.LIMIT controls the number of artifacts to download. The argument to the java -jar command controls the number of download repititions. The class eu.janinko.foobar.httpmetrics.Appache2TaskProvider is the class that uses the httpcomponents-core api.
