slowness in listview

Hi, I have a page where i'm using a listview to populate data into it. whenever i have less number of records like below 100 records to be loaded into a listview my page opens up instantly without any lag, but if the number of records exceeds more than 150 records my page takes a lot of time to open. Is there any way to improve the data loading capacity of the listview, so it can handle more number of data at a time. Microflow doesnot have multiple loops and all, its a simple fetch and populate into list microflow. i'm using a editable listview for my project purpose. Thanks.
