Methods to increase the performance of a Joomla site
Speed and performance of Joomla is largely dependent on the choice of template, followed by addons components / modules / plugins.
-
Number of CSS images, Javascripts (size) marks the final blow to Joomla performance.
-
Activation of inbuilt Gzip and Cache system does speed up the Joomla site.
-
Cleaning up of CSS codes can result in a highly boosted Joomla performance in terms of decreased http requests and total page size.
-
Compression and minification of CSS / JS files, similarly compression and optimization of pics / images is the key to speed up default Joomla.
-
As a demonstration we called two css files with one line of code resulting in 1 less http request.
-
Optimize CSS / JS files to remove the white spaces or comments (which decreases the size of css / js files by 10-40%).
-
Use of the commercial components or other Joomla extensions such as page cache, Query cache, cssjscompress plugin. (which further reduces the loading time and http requests).
-
Combine the CSS / JS files in one (which brings down the http requests).
