Our Magento store running on 1.9.x is using Percona MySQL server 5.6.29 and since our site generates loads of MySQL queries, I need caching as much as possible. I have configured my.cnf like this
# The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock explicit_defaults_for_timestamp = 1 skip-name-resolve innodb_file_per_table innodb_thread_concurrency = 26 query_cache_size = 512M query_cache_limit = 18M thread_cache_size = 64 key_buffer_size = 512M max_allowed_packet = 64M table_open_cache = 2000 sort_buffer_size = 4M read_buffer_size = 4M read_rnd_buffer_size = 2M myisam_sort_buffer_size = 64M max_heap_table_size = 1024M tmp_table_size = 1024M query_cache_type = 1 wait_timeout = 300 max_connections = 200 innodb_buffer_pool_size = 64G innodb_buffer_pool_instances=125 innodb_log_buffer_size=18M # Disabling symbolic-links is recommended to prevent assorted security risks # symbolic-links=0 # Recommended in standard MySQL setup # sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES # Slow Query slow_query_log=1 slow_query_log_file=/var/log/mysql_slow_queries.log [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
Our database size is just 6GB and machine has 120GB of RAM, so I need caching as much as possible to make things quicker. So, does the above configuration fits for BEST caching or is there any value I need to tune or add into?
