I have an app built in ionic 4 in which we have a page where we display all the available items. This item can be range from 0 to 1,00,000. Currently when the list is loaded the app performance goes down by which the app closes unexepectedly.

So I am looking for a solution that can help me to improve the performance of the item loading and rendering.

Maybe you can try using a virtual scroll.

There's a tutorial just here : https://www.youtube.com/watch?v=qgPNdoB1zhk&ab_channel=SimonGrimm

The HTTP request will still get 100 000 items, but you will display just a part of it into your template.

Another way to display it without burning your PC is to use a simple pagination.

If the "app closes unexepectedly", then you need to investigate where the app is crashing. Does the app crash when you request data from the server or after data has been fetched and needs to be displayed on page.
