    Hello Everyone,

    I need a mysql optimization with my server...WordPress installation on my website.

    My server Properties:
    Dell R730
    2 x E5-2620 V3 CPU
    32 GB Ram
    Centos 7

    I use wordpress script.
    instant hit: 1k
    daily visitors: 40.000 Unique

    Code:
    -- MYSQL PERFORMANCE TUNING PRIMER --
    - By: Matthew Montgomery -
    
    MySQL Version 5.6.27 x86_64
    
    Uptime = 4 days 3 hrs 59 min 58 sec
    Avg. qps = 292
    Total Questions = 105160420
    Threads Connected = 10
    
    Server has been running for over 48hrs.
    It should be safe to follow these recommendations
    
    To find out more information on how each of these
    runtime variables effects performance visit:
    http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html
    Visit http://www.mysql.com/products/enterprise/advisors.html
    for info about MySQL's Enterprise Monitoring and Advisory Service
    
    SLOW QUERIES
    The slow query log is NOT enabled.
    Current long_query_time = 10.000000 sec.
    You have 0 out of 105160450 that take longer than 10.000000 sec. to complete
    Your long_query_time seems to be fine
    
    BINARY UPDATE LOG
    The binary update log is NOT enabled.
    You will not be able to do point in time recovery
    See http://dev.mysql.com/doc/refman/5.6/en/point-in-time-recovery.html
    
    WORKER THREADS
    Current thread_cache_size = 1024
    Current threads_cached = 33
    Current threads_per_sec = 0
    Historic threads_per_sec = 0
    Your thread_cache_size is fine
    
    MAX CONNECTIONS
    Current max_connections = 500
    Current threads_connected = 12
    Historic max_used_connections = 45
    The number of used connections is 9% of the configured maximum.
    You are using less than 10% of your configured max_connections.
    Lowering max_connections could help to avoid an over-allocation of memory
    See "MEMORY USAGE" section to make sure you are not over-allocating
    
    INNODB STATUS
    Current InnoDB index space = 480 K
    Current InnoDB data space = 688 K
    Current InnoDB buffer pool free = 99 %
    Current innodb_buffer_pool_size = 2.00 G
    Depending on how much space your innodb indexes take up it may be safe
    to increase this value to up to 2 / 3 of total system memory
    
    MEMORY USAGE
    Max Memory Ever Allocated : 4.49 G
    Configured Max Per-thread Buffers : 875 M
    Configured Max Global Buffers : 4.41 G
    Configured Max Memory Limit : 5.26 G
    Physical Memory : 31.15 G
    Max memory limit seem to be within acceptable norms
    
    KEY BUFFER
    Current MyISAM index space = 324 M
    Current key_buffer_size = 2.00 G
    Key cache miss rate is 1 : 17506
    Key buffer free ratio = 78 %
    Your key_buffer_size seems to be too high.
    Perhaps you can use these resources elsewhere
    
    QUERY CACHE
    Query cache is enabled
    Current query_cache_size = 256 M
    Current query_cache_used = 94 M
    Current query_cache_limit = 8 M
    Current Query cache Memory fill ratio = 36.95 %
    Current query_cache_min_res_unit = 4 K
    MySQL won't cache query results that are larger than query_cache_limit in size
    
    SORT OPERATIONS
    Current sort_buffer_size = 128 K
    Current read_rnd_buffer_size = 256 K
    Sort buffer seems to be fine
    
    JOINS
    Current join_buffer_size = 1.00 M
    You have had 1172 queries where a join could not use an index properly
    You should enable "log-queries-not-using-indexes"
    Then look for non indexed joins in the slow query log.
    If you are unable to optimize your queries you may want to increase your
    join_buffer_size to accommodate larger joins in one pass.
    
    Note! This script will still suggest raising the join_buffer_size when
    ANY joins not using indexes are found.
    
    OPEN FILES LIMIT
    Current open_files_limit = 65536 files
    The open_files_limit should typically be set to at least 2x-3x
    that of table_cache if you have heavy MyISAM usage.
    Your open_files_limit value seems to be fine
    
    TABLE CACHE
    Current table_open_cache = 3072 tables
    Current table_definition_cache = 2048 tables
    You have a total of 479 tables
    You have 973 open tables.
    The table_cache value seems to be fine
    
    TEMP TABLES
    Current max_heap_table_size = 128 M
    Current tmp_table_size = 128 M
    Of 5561736 temp tables, 18% were created on disk
    Created disk tmp tables ratio seems fine
    
    TABLE SCANS
    Current read_buffer_size = 128 K
    Current table scan ratio = 880 : 1
    read_buffer_size seems to be fine
    
    TABLE LOCKING
    Current Lock Wait ratio = 1 : 33
    You may benefit from selective use of InnoDB.
    If you have long running SELECT's against MyISAM tables and perform
    frequent updates consider setting 'low_priority_updates=1'
    If you have a high concurrency of inserts on Dynamic row-length tables
    consider setting 'concurrent_insert=ALWAYS'.

    Can you help me please?

    Hello Micheal,

    Yes, I've tried. But I'm not satisfied.

    You may need to consult with a qualified system administrator or MySQL specialist for additional tweaks to your MySQL configuration if you are still unhappy with the results. You can find a list of system administration services at:

    Thank you.
