Magento web store selling top brands sportwear. The client turned to us with a bunch of problems to fix. The main one was slow site performance caused by various 3rd party extensions and custom functionality. To improve store performance, we optimized both frontend and backend areas of the site that involved CSS and JS optimization and minification, Magento template and PHP code base optimization. As a result, page load time reduced from 15.3 seconds to just 4.8.
