6 Methods To Produce Fast Loading WebPages
Information on why page load time is important and what can happen if page load time is poor, then some tips on how to improve page loading time
With a 56k connection a Webpage should load within 8 seconds. The following methods are all ways you can speed up your page load time.
3. There are several different image formats, the most common are Portable Network Graphics (png), Joint Photographic Experts Group (JPEG) and Graphics Interchange Format (gif). Making sure you use a format that retains the quality of the graphic at an optimal size is vital when it comes to page load time. A gif type image is the smallest format so if your images only contain a few colours then this would be the best choice. JPEGs can vary in quality and therefore file size. You should aim for the smallest size that doesn't reduce the quality of the image. PNGs can provide graphics with transparent backgrounds but have a bigger file size than the two previous formats. Bitmaps (bmp) are another common image file type but take up a large quantity of memory. Fast loading webpages shouldn't hold any images of this file type.
4. A minimal use of images, in particular animated gifs will also decrease page load time. Animated gifs are made up of more than one graphic and therefore have a greater file size. Lower file sizes of graphics will decrease a page's load time. The amount of images being loaded is also worth noting as it also effects page load time.
5. Flash animations or swf files are used more frequently these days than animated gifs. Swfs are a siginificantly greater size than that of animated gifs. They should only be used on a page where absolutely essential. It is worth taking into consideration using an animated gif in oppose to a swf if your animation is short and doesn't require any user interaction. Nevertheless it should also be understood that if your animation uses audio a gif won't be an option. The use of swfs will also require extra code to check if the user has a flash player installed. Further code equates to a greater file size and is therefore another reason to only use swfs where necessary.
6. It is advisable to combine separate images where you can to decrease page load time. Two separate images will have a greater overall file size than one. The more graphics the page needs to load the more http requests it needs to execute and this also increases loading time.
