Introduction
Load testing is one of those steps that should be performed for every major system rollout but rarely happens. In this article, we will demonstrate the basic procedure for load testing web-based applications, using an ASP.NET application as an example.
Why Load Test .NET?
Working for a performance tools company, I have the opportunity to assist many companies with their load testing efforts. A large number of these efforts happen immediately before deployment or shortly after deployment, when live usage has determined that performance is inadequate. Naturally, performing the load testing at this stage in the project is much more costly than … Continue reading »
Determining the CPU cost of virtualization with VMware ESX
The performance of our reference application under load (a default SugarCRM installation) on a virtualized server showed a 14% decrease, measured by total system capacity, compared to the same system running natively on equivalent hardware.

Load Testing SugarCRM and the Zend Optimizer
This article measures the performance impact of the Zend Optimizer on a real-world processor-bound PHP application (SugarCRM) under load. Our measure of performance is user capacity. We define that as the number of simultaneous users that the system can support while meeting the specified performance criteria. The performance critera for this test require that all pages load within 6 seconds and no errors are encountered in the application.

Durham, NC (PRWEB) — Web Performance, Inc. (WPI), the creator of industry-leading Web performance web load and stress testing software, releases its latest investigative research report on Apple’s Safari Web browser. In response to Apple’s claims that its recently released Windows version of the Safari Web browser was the “fastest browser on Windows,” WPI put these claims to test.
Evaluating Apple’s Browser Performance Claims in The Real World
On June 11th, Apple released a Windows beta version of its OSX web browser, Safari 3.0, claiming its the “fastest browser on Windows”. The claims were based on the results Apple found while running the iBench benchmark from Ziff Davis, with separate measurements for HTML, JavaScript performance, and application start time. While benchmarks are invaluable for performance evaluation, we set out to see if those claims would make a difference in actual browser usage.

Durham, NC (PRWEB) – Web Performance, Inc. (WPI) announces the 3.0 release of the Web Performance Suite™, an integrated collection of web testing modules based on the Eclipse Rich Client Platform.
Durham, NC – The Caisse Nationale d’Asurance Vieillesse (CNAV) is the French-equivalent of the Social Security Administration in the US, responsible for managing millions of pensions. After becoming disillusioned with the length of time it took to do a performance evaluation using the open source program OpenSTA, they evaluated the top seven commercial load testing solutions and chose Web Performance Load Tester™ because its "no scripting" approach cut their testing cycle to 1/4 to 1/5 of its previous time.
Measuring the Performance Impact of Virtualizing a Web Application Server
Virtualization is hot. Over the past few months, it would be difficult to pick an IT magazine out of my stack that does not have an article on Virtualization. Even in our small company, we have two VMware servers. This allowed us to reduce 9 underutilized servers down to two physical machines. Because the original severs were severely underutilized, the virtualized servers actually perform better (running on newer hardware). They are easier to manage – especially for backups. We have reduced the risk of configuration changes, software installs and upgrades by … Continue reading »
Durham, NC (PRWEB) – Web Performance, Inc. (WPI) announces the 3.3 release of the Web Performance Suite™, web load testing software that uses advanced analysis of web browser/web server communication to automatically test the most complicated websites without programming.
Part 2: Performance and Distinct Error Handling under Computational Load
In this report the same tests as part one are re-run, this time with no memory limitation showing a marked increase in Tomcat performance on Linux over Windows.
