SiteTester is a load-testing utility designed to
test web servers and web applications. SiteTester
simulates concurrent access of various users from
different hosts to a web/application server. Each
virtual user follows a predefined procedure to
access the server. By increasing the number of
virtual users you can test the capacity of your
servers and determine the extra hardware and
bandwidth needs, if any.
Many web applications fail to operate on
simultaneous uses, despite every effort to test and
debug the application on the development
environment. This is mainly due to the nature of
multi-threaded programming, which makes it difficult
to simulate the actual process. Application codes,
which are not multi-thread-safe, which leak memory,
which may produce deadlocks, have great affect on
the performance and stability of the web sites.
SiteTester allows web application developers to test
their codes amongst many users, and take precaution
before the actual deployment occurs.
