Reducing Startup Latency in Web and Desktop Applications

Application startup latency has become a performance problem for both desktop applications and web applications. In this paper, we show that much of the latency experienced during application startup can be avoided by more e ciently packing application code pages. To take advantage of more e cient packing, we describe the implementation of demand paging for web applications. Finally, we show that combining demand paging with code reordering can improve application startup latency by more than 58%.
