We're using Gallery control to render items stored in a collection by adding labels as a grid. The collection is being populated via Flow and can have around 10,000 items.

When the gallery is rendered, the page hangs and is totally unusable. Is there a workaround for this?

Note: We've already optimized our response time by fetching all the data as JSON and saving it in a collection. We can't use DataTable as the columns being used are dynamic and data table requires us to set columns explicitly.
