Nowadays, it's impossible to further compress your store's javascript and css. We have a simple trick to explore the fallacies of the mind: - When the customer hovers over a link, we begin preloading the page that link is pointing to and once clicked, it will open much faster. - The customers will feel that the page loaded instantly but not because of script and image optimizations. - It works perfectly even if the theme is sluggish and page loading analytics don't yield best marks.
