Google PageSpeed is a family of tools by Google, Inc. [1] designed to help optimize website performance. [2] It was introduced at a Developer Conference in 2010. [3] [4] There are four main components of PageSpeed family tools:
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.
This time is made up of the socket connection time, the time taken to send and the time taken to get the first byte of the page. [1] Although sometimes misunderstood as a post-DNS calculation, the original calculation of TTFB in networking always includes network latency in measuring the time it takes for a resource to begin loading.

Internet rush hour is the time period when the majority of Internet users are online at the same time. Typically, in the UK the peak hours are between 7 and 11 pm. [1] During this time frame, users commonly experience slowness while browsing or downloading content.

LoadRunner is a software testing tool from OpenText.It is used to test applications, measuring system behavior and performance under load.. LoadRunner can simulate millions of users concurrently using application software, recording and later analyzing the performance of key components of the application whilst under load.
Prior to being established as a web standard, web frameworks were generally used to implement lazy loading. One of these is Angular.Since lazy loading decreases bandwidth and subsequently server resources, it is a strong contender to implement in a website, especially in order to improve user retention by having less delay when loading the page, which may also improve search engine ...
Load testing lets you measure your website's quality of service (QOS) performance based on actual customer behavior. Nearly all the load testing tools and frameworks follow the classical load testing paradigm: when customers visit your website, a script recorder records the communication and then creates related interaction scripts.
