It does so happen that we choose templates and extensions for our Joomla project and start building the site, adding more extensions as we go and since most of the development happens on the localhost, site loading / performance does not seem to be an issue. Shock sets in, when the site is moved to live server and tested and having invested 100’s of hours, its way difficult to remove extensions or cut down features to improve site performance. This is the story of most of the people asking for professional help to optimize their sites.
Remember, if it’s heavy... it’s going to load slower.
What should one do?
From day one, keep the site optimization as one of the top priorities. Have tools to measure the effect of each and every addition you make on the site’s overall performance before adding them and try to fix an upper limit for site size and HTTP requests. Here are some of the easy-to-use tools to test your website.
