Performance Impact on sap.m.tree

[Sriharsha_C]

Performance issue:
When the records are more than 20000 in the JSON model. Tree loading took more than 2 and half minutes.

Control name: sap.m.tree
Kindly check sample Code below:

why not using treetable? even with m.tree, it only took 30 seconds for me.

First, from the SAP Fiori Design Guidelines m.tree shall only be used up to 200 items and a maximum of 12 levels. You are far above that. In addition to the treetable solution suggested before, I could also imagine to use a flexible column layout and display lower levels on the object page. Of course, it strongly depends on the use case.

For the performance issue. More than 2 minutes seems to be way to long. Did you check if the backend is performing appropriately?

From backend we get the response in 10 seconds, but it takes 2 minutes in the frontend.

In Above sample, there is no backend involved, just hardcoded the JSON with 20000 items and then using the sap.m.tree to load.
