05 Tips to Reduce Server Load and Save Bandwidth
01. Use CSS Text Instead of Images
Images make your Web pages slower and consumes a lot of bandwidth of your server. Instead of using a background image, use the CSS code. For example if you want to use plain red background in your website then use CSS code background-color:#F00 instead of a red-bg.jpg. With CSS, you can set the background color or background image of any CSS element.
These is a nice tutorial on CSS-Tricks.com about how wisely you can use your background images to reduce server load.
02. Optimizing Your Images
More than half of the bandwidth on most websites is used by images and optimizing images is the best way to improve the bandwidth used on your web server. Optimize your images for the internet and shrink their sizes as well, never use bitmap files (.bmp) as they are HUGE (mostly in MBs). You should use jpeg (.jpg) or gif (.gif) files for images as these are optimized for the internet. A good rule of thumb is to strive for no one image being larger than 10 Kb. This is especially hard with animations, but if you can do it, you’ll notice remarkable difference in bandwidth used of your server. There are various image conversion programs/softwares available all over the internet and there are various optimization programs too, be sure to get an optimization program that will be able to retain the images quality while drastically reducing its size.
If you’re using Photoshop, use can compress your images by ‘Save for Web & Devices’ (Alt+Shift+Ctrl+S) option to optimize it for minimum bandwidth. When you have an image with lots of colours, you should go for JPEG or PNG. Play around with the quality to change the file size.

03. Compress your CSS by shorthand CSS properties
CSS files can be pretty big, with lots of useless breaks and spaces. CSS shorthand properties are great! They’re a great way to reduce the amount of code contained in a CSS document, allowing for faster download times and easier editing. For example you can use
(top, right, bottom, left)
There is a cool article written by webcredible.co.uk about CSS shorthand properties.

04. Remove Unnecessary HTML Code, Tags and White Spaces
You can compresses your page size by removing unnecessary white space in your HTML files even remove comments (if not absolutely necessary) because every extra charecter means extra page size. Whether you use visual HTML editors or notepad, your HTML code contains unnecessary stuff: unneeded spaces, returns, meta tags, default values in HTML elements, etc. They will make your web pages bigger, without serving any real purpose. Bigger web pages takes longer to load, increases data traffic of your web server, and waste precious bandwidth.

05. Cache RSS Feeds
RSS or Really Simple Syndication, as it is commonly known, is a technology that gives webmasters the ability to easily distribute and publish syndicated content on the Internet. Once the feed is cached it will be read from the local hard drive for a specified amount of time. After the specified time has lapsed, the RSS feed will be fetched again. This allows the contents of the RSS feed being displayed to remain current, while expediting the whole process. Cache RSS feeds reduce bandwidth usage. The bandwidth is reduced because the web server does not have to repeatedly fetch the same RSS feed from your server.
