Cache management is an easy way to improve the performance of your site. In Magento2 whenever a cache needs to be refreshed, a notice appears at the top of the workspace to guide you through the process. Refreshing the invalid caches is important.
You can clear the cache by going to the System option in the left panel and then clicking on “Cache Management” field under the tools option.
Here, the Cache Management page shows the status of each primary cache and its associated tag. The large buttons in the upper-right corner can be used to flush the Magento Cache, or the all-inclusive Cache Storage. At the bottom of the page there are additional buttons to flush the catalog product images cache and JavaScript/CSS cache.
After clearing a cache, it is advisable to always refresh your browser to make sure that you can see the most recent files. Clearing the Magento cache does not clear your web browser cache. You may need to clear the browser cache to see updated content.
