This mode hides exceptions, serves the static files from cache only and does not allow you to enable or disable cache types in Magento Admin. The production mode is intended for deployment on a production system. Magento has three running modes, default, developer, and production mode. If it does not change to HIT it means the page is not cached and the cache is not working. Refresh the page, it should change to HIT.Inspect the page headers in your browsers debug network tab.Put the store in Developer Mode on your local or stage environment: You can also test whether or not your page is cached manually. Thus, you can identify if trivial pages have problems with cache. Look for the cacheable="false" attribute in your layouts and see on which blocks they are set and on which pages those blocks are called. This will disable the cache for the whole page that contains that block, not only for that block. For example, If you want to exclude a block from the cache don’t use the attribute cacheable="false" in the XML layout when declaring your block. Make Sure Full-page Cache Works: It’s Easily Brokenįull-page cache can be easily broken in Magento 2. In the Actions dropdown select Enable and click Submit.Select the Cache Type you want to activate.Go To System > Tools > Cache Management.You can also do it from Magento Admin by logging in as an administrator: To enable cache types you can run the CLI command: To enable Magento full-page cache you can run the following CLI command: These are dynamic pages or sections of pages that are user- and session-specific. For example, the cart page will not be cached, otherwise, all users will see the first cached version of the page. This will create cached versions of your pages and will deliver them to the user instead of running all the queries for each request. Using full-page cache as part of your Magento optimization efforts can tremendously increase your website speed. This makes the website response much faster. Full-page cache stores that HTML response, so that the next identical request will directly return it skipping all the back-end processing and database queries. This request is processed by PHP doing specific operations and database queries then returning the corresponding HTML to be displayed to the user. When a user is accessing your store, a request is made to the server. Look into the Model CRUD metrics where you can find insightful data such as load calls into loops. Look how your layout is loaded and which are the template blocks that perform the slowest, then look into that code. Always keep in mind the time and space complexity and build your algorithm in an optimized way. Load the whole collection with everything you need and then loop through it. One of the main things junior developers are doing wrong in Magento is to load models inside loops. Knowing that, you can compact those queries into one, and thus speed up Magento. That helps you identify how many MySQL queries you have on a page and how many are identical. The best way to identify heavy requests is to use a profiler. There are many third-party Magento modules out there with bad code, using deprecated methods, or having compatibility issues with the latest stable version of Magento.
