why is my website super slow to load?

(I fixed an err)

@J. D. I can't understand what this code does, and can't manipulate it as needed, so I'm asking for more help: After applying the code the webpage is showing the repeater's default text while loading (doesn't look good), then showing all results,

then showing only last 5 results and not loading more. Any advice?

(right now it's back to the older code version)

Asaf,

This code retrieves all the items from the dataset, then:

1. It binds the first 5 items to the repeater. Then (after 3 seconds):

2. It binds the first 10 items (5 of them them already bound), Then (after another 3 seconds):

3. It binds the first 15 items (10 of them them already bound)... etc...

can you guide the way? is there a wix tutorial for this? I think for the moment I'll focus on option "2"...

First you get the data from the collection or the dateset (do not connect it to the repeater via the editor). Then when you have the items you can do something like:

let i = 5;
let intervalInSeconds = 2;
const dataBindingInterval = setInterval(() => {bindData()}, 1000 * intervalInSeconds);
function bindData(){
let data = items.slice(0, i);
$w("#repeater1").data = data;
i += 5;
if(data.length >= items.length) {clearInterval(dataBindingInterval);}
}

I tried to do it, but I have several questions: 1.

How to limit the number of items to load? I use this inside the "$w.onReady":

.
.
.
$w("#repeater1").onItemReady(($item, itemData, inx) => {

 // bind data from dataset with code (faster then editor)
        $item("#textName").text = itemData.firstName;
        $item("#textMaxPrice").text = String(itemData.maxPrice); 
        $item("#textFreeText").text = itemData.freeText; 
        $item("#textCity").text = itemData.city; 
.
.
.

and this seems to load all items.

Limiting items to load via dataset in the editor is not working.

2.

Should I use your function inside "$w.OnReady" or elsewhere?

3.

It looks like my website is still very slow, even when I click the "contact" page, which doesn't load any database. Could something else be improved in the website?
