How to optimize multiple json call in a table to load the page faster?

srikanta sahoo_cdx6rg

On a single page, I have a table where each cell content a rest service result display using JSON table and table transformer macro. I gave wit 48 call takes around 5 minutes. Is thee a way to optimize the performance that takes less time. Like add a button the cell and once the user clicks the button, then  only we call the macro to display the result.

Attached the current view of the page.

It‘s hard to tell without knowing the underlying details. 48 calls does not look that much in my opinion.

Ask yourself the following questions:

- Is it possible that the answers are too big so that to much data needs to be transferred over the line?

- Do the calls cause some database request with a missing index so that the answers are small but it takes a long time to find the needle in the haystack?

- Can you make a single request that gives you all answers at once and then iterate over the data to fill you table?

- Is it possible to cache the data? Can you provide a server that periodically pulls the source system once an hour and then stores the results for your overview.
