Prep your Web apps for stellar performances
Load testers prove a valuable part of your development strategyFollow @infoworld
I found that each approach was solid and the different methods were complementary to one another. For example, after recording and executing a script, I was able to identify one area of my test Web site that was performing slower than expected under load. Using manual script creation, I was then able to focus a second round of testing on just that portion of the site.
Likewise, after defining the test site URL and the depth to scan in the Web Crawler utility, PureLoad accurately captured the content and structure of my site. I was then able to add some tasks manually to provide variable input during a load test from a file.
During the tests, PureLoad provided data and charts as it recorded the results of the execution. I was able to view overall metrics, such as successful and failed tasks and response time data, or drill down to the individual virtual user level to view the same types of metrics. At the conclusion of the test, the same metrics were then available for review and exporting.
Overall, PureLoad's reporting metrics are not as detailed as those found in Proxy Sniffer, but most testers should find them more than adequate.
PureLoad includes a load-test comparison tool, and after comparing the output of several load test runs, I found it to be on par with the comparison functionality provided by Proxy Sniffer. I also found it useful to export test data from PureLoad to a series of spreadsheets (CSV) and chart images (PNG) to perform further trend analysis.
Sites considering adoption of load-testing tools should evaluate PureLoad. In particular, its strong scripting facilities and added capability to support performance testing of both Web and enterprise apps make it appealing.
Any of the three tools tested here would be a useful addition to the toolboxes of enterprise performance-testing teams. OpenSTA provides solid core of Web load-testing tools at a budget-minded price, whereas PureLoad is an ideal fit for load testing Web and other enterprise technologies. Teams that need a full-featured Web load-testing tool at a reasonable price should definitely give Proxy Sniffer a test drive.
