Magento 1.x and Magento 2.0 are fully baked e-commerce platforms and despite having some many built-in functions, the platform renders amazing speed and performance for any shopping cart website. The Magento Cache management plays a very important role in improving the performance of your website and it is very critical that the cache management is ideally utilized.
Magento uses by default the two level cache. Each cache backend has it’s own roles and functions. APC and Memcached are key/value cache backends, they don’t support tagging (grouping of cache entries). File system and Redis has tagging support. By default, Magento stores it’s cache entries in the file system, you find the cache in var/cache/. so whenever a cache needs to be refreshed, a notice will appear at the top of the Magento admin to flush the cache. Follow the link to Cache Management, and refresh the invalid caches.
In the Magento admin, you see two options:
- Flush Magento Cache
- Flush Cache Storage
In some events, the services such as Memcache is shared with other applications using a common location like “/tmp/”. It removes all items in the default Magento cache (var/cache) and the var/full_page cache that have a Magento tag. Flush Magento Cache on the other hand will basically removes only those entries that Magento reliably tracks as it’s own. “Flush Cache Storage” meanwhile clears everything including one that are shared with others as well.
- To Flush the cache, follow the steps:
- Login to Magento backend
- Go to System and under Tools, click on Cache Management
You can use Flush Cache Storage and Flush Magento Cache option depending upon the requirement.
