Refresher Pull-To-Refresh with large content

Hey everyone, I just started to implement the pull-to-refresh feature and noticed that when I have a large amount of content on my ion-content the pull down is lagging. I’ve started to read up through the forums about what could cause this, but haven’t found a working solution.

The ion-content is comprised on multiple horizontal ion-scrolls with ion-cards in them. I did see some mention of box-shadow being expensive so could be something to do with that. (When I test with less content everything is smooth)

Any ideas are appreciated! Thanks.
