Magento Optimisation

Cache is kind of a storage that keeps information about web pages on the Internet. For example, once you enter a desired webpage, the browser remembers files you had access to while viewing that page. Next time you come back and visit the same page, your browser will pull the same files from cache instead pulling them out of the original server. In other words, caching helps in storing user’s activity, while the user is on a particular web page. Magento allows users to enable caching by various ways such as browser caching, magneto cache, Redis, varnish, etc.

Examine and identify the bottle necks in your code both front- and back-end. Enabling compression is like putting your website into a zip file. Compression can dramatically reduce your page’s size and thereby increase its speed. Gzip compresses web pages and stylesheets at the server level before sending them over to the browser. Use a PHP accelerator like Zend and uninstall unnecessary PHP or Apache modules you don’t need or use. Improve your database performance using query indexing and broad optimization scripts. Merge your JavaScript and CSS files as this will reduce the load time dramatically since its loading only one merged file instead of numerous JS and CSS files across your Magento store.
