Ionic 2 improve slow transitions between lists

HI all,

I’ve been playing around with ionic2 and I am impression with the speed of development.

How ever I’m struggling in making the app fluid.

My issues is the following I have 2 tabs on with a long lists (I use infinity scroll and load 30 or so items at once). I store the long json in an array in the page component.

as soon as my pages are loaded with content transition become unbearably slow. What is the best practice? Is this caused by ngFor? Do I need to empty the array variable on page leave?

thanks in advance.

I think I found the issue I made sure http request were fired onPageLoaded().
