Ion-select with 1500 entry very slow on ios

I have a json list having about 1500 entry, I am loading this list from a web-service then displaying it in a select tag, the problem comes on ios,
Loading the list and displaying it on iphone6 take about 5 minutes, but on Android it is working well.

Any suggestions for handling large list selection on iOS ?


I think this is due to the DOM objects created inside the select control.
My suggestion is display the list of choices via modal and list the items inside using virtualScroll.
A virtualscroll implementation of the select control would be nice.

Loading the data itself take very long time on IOS, I am using regular http request.
