Understanding and Reducing Web Page Latency

Studies have shown that surfers spend a lot of time impatiently waiting for Web pages to emerge on screen and HCI guidelines indicate ten seconds as the maximum response time before users lose interest. This paper presents research into the observed usage of Web images and the effect on page retrieval times. The prevalent factor that affects how quickly a Web site performs is the type of Web hosting environment that the site is deployed in. Web users are faced with sliding scale of delays in reality, with no one Web page taking the same time to load on two separate occasions. It is arguable that the magnitude and variance of network delay between a client and server are generally proportional to the distance spanned, assuming that all other influencing factors remain constant. Web can tweak their content to reduce the loading time of their sites.
