Factors that affect the speed of the web site
Technical factors – the quality of the hosting package: speed of the web hosting server machine, number of web sites hosted on the same machine, Internet connection bandwidth (speed) available to the hosting provider and to the customers in their hosting packages
Software and design factors – quality of the web design and web programming. These are the factors that directly depend on the persons involved in the web Web site /web page/ optimization for speed
Web page graphics objects – pictures, images, photos, charts, etc. These are the most common objects that increase the web page total size and cause delay when it loads in the browser. The total size of one web page should be kept less than 50K that will guarantee the page can be loaded for less than 10 seconds using Internet with speed 56Kb/s. To achieve this recommendation consider the following basic rules:
Keep the number of different pictures in one web page as less as possible
Keep the picture size (in pixels) small, this will decrease the picture file size as well
Keep the number of colors in the pictures small. This has direct impact on their file size.
Reuse the images in the different web pages where it is possible, especially where the images are used for background formatting. Once the image file is downloaded to the visitors computer, it will be cached and its local copy reused afterwards for the next web pages opened from the same web site
The total size of all images in one web page should be less than 30K. This will left another 20K to be shared between the web page code elements and the web page content.
The web page code is not visible for the visitors. They see textual content and images only. Hence, to left more room for the actual web site content, it is important to optimize the web page code elements too.
