Web performance refers to the speed in which web pages are downloaded and displayed on the user's web browser. Web performance optimization (WPO), or website optimization is the field of knowledge about increasing web performance.
Faster website download speeds have been shown to increase visitor retention and loyalty[1][2] and user satisfaction, especially for users with slow internet connections and those on mobile devices.[3] Web performance also leads to less data travelling across the web, which in turn lowers a website's power consumption and environmental impact.[4] Some aspects which can affect the speed of page load include browser/server cache, image optimization, and encryption (for example SSL), which can affect the time it takes for pages to render. The performance of the web page can be improved through techniques such as multi-layered cache, light weight design of presentation layer components and asynchronous communication with server side components.
