Increase website loading speed

  • Blog

There are various options for determining page loading speed, and here we will look at how to maximize it. Next, we will analyze the points for specific actions to achieve the result, located as they are significant in solving this issue.

Image Optimization

It is on the size (weight) and number of images, first of all, the speed of loading the site. The larger and sharper the image, the longer it will open. But here it is desirable to find a “middle ground” and not degrade the quality of the graphics so much that the submitted content will lose its appeal. If, even using Photoshop or any other graphics program, you cannot independently carry out their normal optimization, save everything in the initial version or try to use the service provided by Yahoo. It will reduce their weight as much as possible, but maintain the quality with the existing extension.

CSS and JavaScript optimization

These actions usually do not significantly increase the speed of the site, but increases Page Speed. To optimize CSS, you can use any free online services (they are now enough on the Internet). They will clear your pages of unnecessary spaces and reduce the information provided, where possible. Of the recommended ones, you can use cleancss.com, iceyboard.no-ip.org (without the “Output using smallest size” checkmark!), Cy-pr.com, YUI Compressor. You can optimize your JavaScript code with jslint.com, recommended by Yahoo, or closure-compiler.appspot.com, offered by Google.

To increase the speed of the site, you should not use asynchronous loading of CSS, JS with the main content of the page (text, tables, pictures, etc.). This will achieve the goal, and the content will start downloading almost immediately. But, if the user sees the text with the image and clicks on something, and the loading of styles and scripts is not over here, he will most likely get an error and everything will have to start all over again.

Caching function

When you open a fragment of any site, all of its elements (graphics, texts, CSS styles, and much more) are loaded into the cache of the user’s browser. When a message arrives from him that the browser should save this information for a certain time, it is downloaded to the user’s computer and the site’s download speed will increase significantly on subsequent visits to the resource. In this case, only the changed data will be loaded again, the rest will be taken by the browser from a saved file called a cache.

Gzip archiving

A method that requires mandatory and instant archiving of information sent to computers of users trying to view the contents of the browser on the server that stores your site. When this option is enabled, the server transfers all files in a compressed form, and client browsers unpack it and they see the pages of your resource much faster. It should be borne in mind that the use of a method that allows you to speed up the site, involves an increased load on the hosting server. Therefore, in order for your resource to remain constantly available, you must choose a hosting with a good supply.
