[Issue] ion-content can't scroll (not response) with large text data


My app work with a large database. The string that I bind into scope is very big (~40k chars).
I don’t know how to solve my problem. It works perfect with the string lower than 10k chars.
When I tap on the screen, move the finger, I have to wait a little bit (~10s) to see it scroll. But other content like header button or some thing else out-side the ion-content is work fine.
Note: It is easier when I tap on the right side and scroll (near scroll-bar). But moving the finger to middle of screen it is really slow to response (almost can’t scroll). When add overflow-scroll=“true” it has same problem.
Please help me solve this problem
