I have a page where i'm using a listview to populate and display data from a entity via association. whenever i have less number of records like below 30-40 records to be loaded into a listview my page opens up instantly without any lag, but if the number of records exceeds more than 100 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. i'm using a editable listview for my project purpose.
