Multiple ion-slide-box rendering very slowly

I’m creating a simple app that lists users in a table and let’s them swipe left or right on their icon to sign in or out.

I’m using the ion-slide-box control for this, but it is very slow to render initially.

On an iPad this performance problem makes the initial load time 10+ seconds.

It seems some of the problem is that $digest is being called every time an item is added, rather than after all the items in ng-repeat are finished.

A simple JS fiddle showing the performance problem:

Note: in my app, i am shownig a table with many boxes visible at once, so collection-repeat is not an option.

The loading time seems to scale with more items, OR more ion-slides in the template.

I’m looking any possible solution to improve the rendering time!
