interface performance

Check the performance view and optimize your code. docs.appian.com/.../Performance_View.html

Do you have any specific question?

Firstly you need to establish if there is a performance problem. 

Once you have you then need to determine where in the stack that the performance problem is. A poorly performing user interface maybe due to latency issues in the network or in the database. Or it maybe the way the user interface is constructed.

The Appian User Interface Designer comes with a 'Performance' view which will tell you where the time is being spent from the time the interface starts to load to the time it has finally loaded. This can help you pinpoint where there might be issues, but only if you're sure the problem is in the user interface.
