The query cache has huge scalability problems in that only one thread can do an operation in the query cache at the same time.\\\n***InnoDB Dictionary Size***: The data dictionary is InnoDB ‘s internal catalog of tables.

If you have a cache set to 500 but it has 10 instances, each cache will only have 50 cached.\n\nThe `table_definition_cache` and `table_open_cache` can be left as default as they are auto-sized MySQL 5.6 and above (ie: do not set them to any value).",
