testing architecture based on Common Object Request Broker Architecture
(CORBA). OpenSTA is an open source software licensed under the GNU
General Public License. It is designed to generate realistic, heavy loads,

OpenSTA graphs both virtual user response times and resource utilization
information from all server systems under test. This feature facilitates the
gathering of precise measurements during load tests and the analysis ...
