Answer 2

Pagination is the way to go, don't load everything at once and load only required fields from Catalog

Answer 3

try to use pagination or create a collection of beans that only hold the data that you really need

For example if you only display field1, field2 and field3 or your Catalog then create a bean with only these fields
