Ion-content transition issue

We developed apps with ionic and angularjs, but we have some issue with transition content it makes content comes down from top, but it is very slow transition, and have lag.

I think it causes the ion-content, when I remove it transition was gone, but I can’t scrolling the page.
Is it possible to remove transition ion-content?
and how I can do that?

this is the sample image when I get it come from top screen

Thank you.
