Under System Status I am seeing something that I know nothing about. Has to do with PHP opcode and PHP user cache. Below are the messages respectively for each. Could someone point me to a post on this forum or elsewhere that will explain what I am supposed to do for these two areas of the System to become compliant for performance enhancements for B2E?

"Using an opcode cache allows all your PHP scripts to run faster by caching a "compiled" (opcode) version of the scripts instead of recompiling everything at every page load. Several opcode caches are available. We recommend APC (which is included with PHP starting from PHP 7)."

"Using an user cache allows b2evolution to store some cached data (Block Cache) in memory instead of regenerated the blocks at each page load. Several user caches are available. We recommend APCu (which needs to be enabled separately from APC, starting from PHP 7)."

If I am going to have troubles with visitors leaving or other search engine related negatives due to me not understanding about PHP coding or getting my hosting provider to turn on certain features of my hosting package then I really need some guidance to prevent this from hindering my site performance.
Thank You
