Before you consider scaling, you should understand your system performance and potential system bottlenecks. https://webpagetest.org/ evaluates your site and creates a detailed report. The report helps identify images you can further compress and the impact of your system caches, as well as potential benefits of compressing text.
Use WebPagetest to evaluate two or more websites. In one page, discuss how the report’s findings align with your user experience.
This evaluation should be written using APA formatting. Be sure to include a Title Page and Reference Page.
