In this section, we demonstrate how DeBox's features can be used to analyze and optimize the behavior of the Flash Web Server. We discover a series of problematic interactions, trace their causes, and find appropriate solutions to avoid them or fix them. In the process, we gain insights into the causes of performance problems and how conventional solutions, such as throwing more resources at the problem, may exacerbate the problem. Our optimizations quadruple our SpecWeb99 score and also sharply decrease latency.
