FORCE or OPTIMIZE TABLE to defragment tables for better performance OPTIMIZE TABLE `c2stickdb`.`wp_options`; -- can free 74.958984375 MiB Total freed space after defragmentation : 74.958984375 MiB MySQL was started within the last 24 hours: recommendations may be inaccurate Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1 We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found. See https://dev.mysql.com/doc/internals/en/join-buffer-size.html (specially the conclusions at the bottom of the page). When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries which have no LIMIT clause Performance schema should be activated for better diagnostics Consider installing Sys schema from https://github.com/FromDual/mariadb-sys for MariaDB Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU Variables to adjust: skip-name-resolve=1 join_buffer_size (> 256.0K, or always use indexes with JOINs) tmp_table_size (> 16M) max_heap_table_size (> 16M) table_definition_cache (400) > 783 or -1 (autosizing if supported) performance_schema=ON key_buffer_size (~ 88M) innodb_buffer_pool_size (>= 7.5G) if possible. innodb_log_file_size should be (=1G) if possible, so InnoDB total log files size equals 25% of buffer pool size.
