Optimizing Websites
Description
-----------
Optimising your website's files is very important for better
utilisation of server resources. Even a high end server can
fail to deliver the speed and performance that you look for,
if the site is not optimised.
Procedure
----------
Images :
--------
[1] Do not scan and directly upload the images to the server.
Always compress the file to lower space occupying format such
as .jpeg or .gif.
[2] As a thumb rule, save an image with photograph or more
colors as .jpeg. Since JPEG format has more colors in its
color pallatte, it will occupy less file size. Hence it will
download faster.
[3] Save an image with text or less color as .gif. Gif is a
highly compressed format. Since texts have less colors gif
will compress them to the lowest possible size and this will
enable faster download.
[4] Never use images in formats other than .jpeg, .gif, .png.
[5] Always work and save your images with 72 dpi. More than
this will not make any difference in quality of the picture as
far as web is concerned.
[6] Do not save as one single image file. Cut the same image
into pieces and assemble them in FRONT PAGE or DREAM WEAVER.
[7] Some designers use automated tools to slice the images.
This affects the site performance drastically. Too many small
images will end up in more downloading time than fewer
numbers. Hence, number of pieces must be chosen optimally.
[8] Do not use more than 7-9 images per page in your photo
gallery.
[9] Use thumb nails to show preview. Let the visitor decide
which one to be seen at high resolution.
Html Pages:
-----------
[1] Do not stack all the contents in on single page. Split the
pages into different menus.
[2] Programs such as Front Page and Dream Weaver have
indicators that will show the downloading time for the web
pages that you create in them. As a thumb rule a single HTML
page should not exceed more than 30 KB. However, this is not
applicable for manuals or documentations. But avoid opening
these file from your website. Alternately, you can allow the
user to download and then open in his/her desktop. |
