Our engineers are making some changes to our RESTful service calls, so on one page we are making many calls to get different contents through different AJAX calls to fetch small amounts of data, instead of fetching all the data at once. This way is supposed to help us improve the loading speed.

However, while waiting for the responses, they suggest adding spinners all over the page. From my point of view, too many spinners with different sizes makes the page busy and distracting.

I don't know what the UX experts would say about this.
