Performance

abap2UI5 is fast! Almost everything is processed in the backend, leveraging the ABAP stack, which performs significantly faster than client-side or browser-based processing.

Frontend logic is kept to a minimum: no business logic is executed, and everything is passed directly to the UI5 framework, focusing solely on UI rendering.

abap2UI5 has been successfully tested with tables containing large numbers of entries and columns. So, you can confidently develop your app — performance should not be a concern.

Suggestions

If you still want to optimize your app, consider the following tips:

• Only call the client->view_display method when necessary. Instead, prefer using client->model_update so that the UI5 framework only re-renders the controls that have actually changed
• Prefer using client->bind and use client->bind_edit only when users need to make changes that are processed in the backend. Otherwise, it leads to unnecessary data transfers
• Declare public attributes in your app class only for variables displayed in the frontend. This helps prevent the framework from accessing unused values
• Follow standard ABAP best practices, such as reducing loops and using sorted tables, as you would in any other ABAP development project
