Trace Technologies. GUI-based tool for load/Performance /Stress/ Scalability testing of web applications. Using this tool more number of virtual clients can be generated to hit the web server at a specific time. It simulates multiple instances of web client accessing a Web Server based on the simulating information obtained from one web client during a session with a web server. So under various load or stress condition, any web application can be tested effectively. This tool is developed into three modules, Load Tracer- Recorder, Load Tracer-Generator, and Load Tracer- Analysis. Load Tracer is compatible with Internet Explorer and Netscape.
Microsoft Application Center Test Microsoft Designed to stress test Web servers and analyze performance and scalability problems with Web applications, including Active Server Pages (ASP) and the components they use. Simulates a large group of users by opening multiple connections to the server and rapidly sending HTTP requests. Supports several different authentication schemes and the SSL protocol, making it ideal for testing personalized and secure sites.

OpenSTA. A distributed software testing architecture based on CORBA. OpenSTA is designed to be used by Performance Testing Consultants or other technically proficient individuals. Using OpenSTA a user can generate realistic heavy loads simulating the activity of hundreds to thousands of virtual users. This capability is fully realized through OpenSTA's distributed testing architecture. OpenSTA graphs both virtual user response times and resource utilization information from all Web Servers, Application Servers, Database Servers and Operating Platforms under test, so that precise measurements can be gathered during load tests and analysis on these measurements can be performed. OpenSTA is Open Source software licensed under the GNU General Public License.
