-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
    MySQL started within last 24 hours - recommendations may be inaccurate
    Dedicate this server to your database for highest performance.
    Reduce or eliminate persistent connections to reduce connection usage
    Adjust your join queries to always utilize indexes. Please note this
    calculation is made by adding Select_full_join + Select_range_check
    status values and triggered when the total >250
    Temporary table size is already large - reduce result set size
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Performance should be activated for better diagnostics
    Consider installing Sys schema from https://github.com/mysql/mysql-sys
Variables to adjust:
    max_connections (> 1000)
    wait_timeout (< 1800)
    interactive_timeout (< 28800)
    join_buffer_size (> 2.0M, or always use indexes with joins)
    performance_schema = ON enable PFS
    innodb_log_file_size * innodb_log_files_in_group should be equals to 1/4 of buffer pool size (=12G) if possible.
    innodb_buffer_pool_instances(=24)
    innodb_log_buffer_size (>= 16M)
