Selection of design pattern(Gof) in below scenario

I need help with a Exam problem:

Let's suppose you are building an E-commerce web application which contains thousands of products in database. A web page displays 100 products in current view of products listing. Upon scrolling down event it loads next 100 products from database and displays. products listing web page shows product name, price and thumbnail image. Web page response gets slow on scrolling or refreshing due to fetching data from web server. Which design pattern strategy(GOF) you will chose to make your webpage loading fast every time when user refresh or scroll webpage?
