Independent Performance and Scalability Testing
Vermont Systems WebTrac Application
WebTrac is a web-based recreation management application developed by
Vermont Systems, Inc. (VSI). WebTrac provides web access to VSI’s suite of
parks and recreation management software, allowing municipal governments,
military, and other organizations to provide direct access to recreation
services via the web. The popularity of Internet enrollment capabilities can
lead to significant usage by citizens during registration periods.
Application bottlenecks or insufficient hardware resources can potentially
slow user interactions or cause servers to crash, resulting in dissatisfied
customers. VSI has over 975 successful installations and was developing the
latest version of WebTrac for their customers.
VSI needed WebTrac to provide high system availability during peak
registration periods. In addition, VSI wanted to correctly size the hardware
requirements recommendations for their customers, so customers would be able
to support expected user loads without over spending scarce resources on
hardware. To accomplish this, VSI needed an objective assessment of the
performance characteristics of the new WebTrac version under heavy loads.
They also wanted to provide their customers with an objective evaluation of
their systems. Using Alterion, Inc. to build and execute load and performance
tests met these needs.
Based on substantial experience with performance testing, Alterion developed
a load model methodology that closely simulated real-world conditions. Using
automated test tools, Alterion created virtual users that logged into the system,
conducted searches, enrolled in activities, and completed credit card purchases.
Engineers then executed the tests against the system with increasing numbers of
concurrent users. By monitoring the virtual users and the WebTrac system,
Alterion was able to provide VSI management with a detailed picture of the
performance characteristics of WebTrac under increasingly heavy registration
Alterion was able to test the WebTrac application under significant and
realistic user loads. The detailed results provided VSI management with
information usable by both their developers to tune application code, and their
customers to plan for the hardware needs under various load conditions. The
performance tests and results enable VSI to provide a superior WebTrac
experience to their customers.
