Proxy Sniffer is a web load and stress testing tool that uses a browser based interface. It enables you to analyze the performance characteristics and stability of your (local) webserver under various load conditions in order to tune web applications. It also comes with a built-in session recorder that captures the data between your browser and a web server. The recorded web surfing session can be transformed into a Java load test program, which can then be compiled and executed. All measured performance data and errors during a test-run are stored inside a single result file, from which consolidated detailed statistics and diagrams can be created. You should have a basic understanding of Java programming in order to get adequate use out of the software. The free version is limited to tests on localhost and has limited user connections for testing. Make sure to read the PDF documentation before getting started. The full version starts at about $3000 per node.
