RUBiS is an auction site modeled after eBay.com used to benchmark e-commerce Web site technologies. It is currently used to evaluate design patterns, application servers, and communication layers scalability. Several implementations using PHP, Servlets, Enterprise JavaBeans (EB BMP, EB CMP, MDB, SB, EJB 2.0 CMP, Session Façade, etc.) are already available and new versions for JDO and .Net are currently developed.
lb is a very small and efficient libevent-based benchmarking tool for HTTP servers. It has been implemented with the main goal to provide a safe and quick replacement for the Apache 'ab' tool. Since its first release, it comes with the ability to benchmark several HTTP servers at the same time, theoretically limited only by operating system limits.
