Average Time Between Page Requests

Average time between page requests is how often, on average, a user requests a page from the Portal Server. Pages could be the initial login page to the portal, or a web site or web pages accessed through the Portal Desktop. A page view is a single call for a single page of information no matter how many items are contained on the page.

Though web server logs record page requests, using the log to calculate the average time between requests on a user basis is not feasible. To calculate the average time between page requests, you would probably need a commercially available statistics tool, such as the WebLoad performance testing tool. You can then use this figure to determine the number of concurrent users.

To perform stress testing, you can use the SLAMD Distributed Load Generation Engine. For more information about SLAMD, see http://slamd2.dev.java.net/.

Page requests more accurately measure web server traffic than “hits.” Every time any file is requested from the web server counts as a hit. A single page call can record many hits, as every item on the page is registered. For example, a page containing 10 graphic files records 11 “hits”—one for the HTML page itself and one for each of the 10 graphic files. For this reason, page requests gives a more accurate determination of web server traffic.
