User Side Factors:
Download Speed
If the user doesn’t have very good downloading speed, web pages won’t load up as quick and things like videos and pictures will take longer to load.
Browser
Certain browsers will not always support different file types used in websites like flash videos; this can be fixed by either using different browsers, or downloading a flash player.
Cache Memory
This helps to load different website pages that are visited more often than others. If the user visits a lot of pages it is a good idea to configure a higher cache memory capacity which is in the browser settings.
Processor Speed
If the user doesn’t have a very good processor, web pages will take considerably longer to load up and show content due to the amount of calculations made per second. A better processor would make web pages load faster even if they contain images and videos.
Server Side Factors:
Available Bandwidth
Bandwidth determines how much the user can download using their ISP. Having a higher bandwidth you can download more data in the same amount of time. Even if you have a high speed internet and a low bandwidth it will still be restricted to a slow download speed.
Executions to be performed before Page Load
Before the web page is fully loads different parts of the page must be loaded first. Like the head, this hosts the CSS and JavaScript, and then the body. This is why a web page that loads slowly will only display the background and colours at first and it will show the structure. Then followed by the body which holds information.
Number of Hit
The number of hits on a web page is basically the number of requests sent by a user's computer to the server hosting the web page. While it does not tell you the exact number of people using the web page but it does give a rough estimate.
File Types
As I said before certain browsers will not be able to show certain file formats, sometimes there are problems with not being able to view images, videos and audio, this is due to the user. It depends on the server side factor as the web page creator has to choose what file types they use.
