IE Performance Tip: avoid repeating <img> tags
This tip is more for those users who have developed a sophisticated data-crunching interface to their app. On one screen, for simplicity, the app gives a long list of data, without pagination controls being created by the user (such as a “View All” feature). To keep it pretty, each line has a visual icon or some surrounding images. Sound familiar? For example, let’s say the list is created by a testing system, indicating which tests were passed and which failed. The list may look something like:
For this example, we’ve … Continue reading »
Persistent Connections & Performance
Reaping performance benefits from using persistent connections on your HTTP web server is nothing new. In a recent test of a SSL site, one of our clients enabled persistent connections on their servers as part of a new deployment. The results were quite impressive: for a single user & negligible server utilization, page durations dropped from 12 seconds to only 3.5 seconds. Persistent connections can contribute to much of this duration difference by reducing the amount of time needed establish new connections. The use of SSL makes this feature even more important, … Continue reading »
Why is my Page being Hit more than Once per View?
During testing of some sites, we found an strange case where pages seem to download themselves. What does this look like?

This has an obvious problem: the dynamic content is being requested twice as many times as necessary, causing the server to have to render it twice as often as necessary. If users turn off Load Tester’s “streaming” feature while recording, this looks a little different: the 2nd instance of the … Continue reading »

The performance improvements in the latest browsers (Internet Explorer 8.0 and Firefox 3.5) have been eagerly awaited for many months…though they come at a price.
New Load Tester feature – web page performance goals
Load Tester has supported the concept of a performance goal for quite a while, but the implementation has been rather limited. We have completed work on an improved version for our next release (3.6). Load Tester now provides the ability to set a performance goal for each web page and/or transaction in a testcase individually. Of course, you can still specify a global page performance goal, as you could in the past. In addition, users can specify a default page (or transaction) duration goal for an entire … Continue reading »
