Improving load time of SPAs : An evaluation of three performance techniques

Abstract: The code size of single page web applications are constantly growing which do have an negative effect on the load time. Previous research have shown that load time are important to users and that a slow application will lose potential customers even before it has loaded. In this paper three architecturally far-reaching techniques are measured to see how they can improve the load time and help to decide if an application should be built with one or more of the tested techniques which are HTTP2 push, Code Splitting and Isomorphism. The experiment shows that Isomorphism can provide a big improvement for the time to first paint and that Code Splitting can be a useful technique for large code bases on mobile phones.
