Optimizing application load time
Improve the performance of your application by reducing content that is difficult to render. By running preflight optimization, you eliminate unnecessary static content and improve load times, which creates a better user experience.
- In the header of Dev Studio, click .
- On the Preflight Optimization screen, click Add optimization.
-
In the
Add optimization configuration
dialog box, complete the
following steps:
- On the Basic tab, in the Access group
list, select the access group that you want to optimize. The associated portal name is displayed on the right.
- Under Optimize, specify whether you want to optimize JavaScript files, Cascading Style Sheet (CSS) files, or both
- Optional: To reduce the size of your JavaScript files by removing comments and other unnecessary elements, select the Use JS Compacting check box.
- On the Advanced tab, select individual rules for the
analysis of the application's design-time model. The Skip option determines if the rule is excluded from the analysis.
-
Click
Submit
to save the optimization's configuration and
start the analysis.
If you run the access group's preflight optimization for the first time, or if you select the Use JS Compacting check box, the process might take a few minutes.
- On the Basic tab, in the Access group
list, select the access group that you want to optimize.
- Optional: To return the application to its previous JavaScript and CSS usage temporarily, clear
the Enable check box on the Preflight
Optimization screen.
You might complete this step if you encounter problems in the application and want to isolate them for testing and correction before you repeat the optimization process.
- Rerunning a preflight optimization
If you change the access group's portal, the application, or the application’s skin after running the preflight optimization process, repeat the preflight optimization to remove any unnecessary static content or add necessary static content introduced by your changes.
- Checking results and JavaScript file dependencies
View the preflight optimization report to see a list of components by category and to compare the static content’s original size to its optimized size.
- Improve application loading time with preflight optimization
Most of the static content for an application—the JavaScript files and Cascading Style Sheet (CSS) files—loads when the user starts the application. By using preflight optimization to reduce unnecessary static content, you can speed up your application’s initial display time, which can be especially important for applications that users access occasionally or just once.
