What is website speed?
Network performance refers to the speed at which web pages are downloaded and displayed on the user’s web browser. Web performance optimization (WPO), or website optimization, is an area of knowledge about improving network performance.
Faster website download speeds have been proven to increase visitor retention and loyalty as well as user satisfaction, especially for users with slow Internet connections and users with mobile devices. Network performance also results in less data being transmitted on the network, which in turn reduces the website’s power consumption and environmental impact. Some aspects that can affect page loading speed include browser/server caching, image optimization, and encryption (such as SSL), which all affect page rendering time. The performance of web pages can be improved by technologies such as multi-layer caching, lightweight design of presentation layer components, and asynchronous communication with server-side components.
