            -- MYSQL PERFORMANCE TUNING PRIMER --
                 - By: Matthew Montgomery -
    
    MySQL Version 5.6.27 x86_64
    
    Uptime = 0 days 2 hrs 48 min 22 sec
    Avg. qps = 0
    Total Questions = 892
    Threads Connected = 3
    
    Warning: Server has not been running for at least 48hrs.
    It may not be safe to use these recommendations

    runtime variables effects performance visit:

    SLOW QUERIES
    The slow query log is NOT enabled.
    Current long_query_time = 10.000000 sec.
    You have 0 out of 913 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 = 9
    Current threads_cached = 0
    Current threads_per_sec = 0
    Historic threads_per_sec = 0
    Your thread_cache_size is fine
    
    MAX CONNECTIONS
    Current max_connections = 151
    Current threads_connected = 3
    Historic max_used_connections = 3
    The number of used connections is 1% 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 = 1.47 G
    Current InnoDB data space = 1.28 G
    Current InnoDB buffer pool free = 77 %
    Current innodb_buffer_pool_size = 32 M
    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 : 60 M
    Configured Max Per-thread Buffers : 169 M
    Configured Max Global Buffers : 57 M
    Configured Max Memory Limit : 226 M
    Physical Memory : 1.30 G
    Max memory limit seem to be within acceptable norms
    
    KEY BUFFER
    Current MyISAM index space = 118 K
    Current key_buffer_size = 8 M
    Key cache miss rate is 1 : 16
    Key buffer free ratio = 81 %
    Your key_buffer_size seems to be fine
    
    QUERY CACHE
    Query cache is enabled
    Current query_cache_size = 1 M
    Current query_cache_used = 16 K
    Current query_cache_limit = 1 M
    Current Query cache Memory fill ratio = 1.64 %
    Current query_cache_min_res_unit = 4 K
    Your query_cache_size seems to be too high.
    Perhaps you can use these resources elsewhere
    MySQL won't cache query results that are larger than query_cache_limit in size
    
    SORT OPERATIONS
    Current sort_buffer_size = 256 K
    Current read_rnd_buffer_size = 256 K
    No sort operations have been performed
    Sort buffer seems to be fine
    
    JOINS
    Current join_buffer_size = 260.00 K
    You have had 0 queries where a join could not use an index properly
    Your joins seem to be using indexes properly
    
    OPEN FILES LIMIT
    Current open_files_limit = 5000 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 = 2000 tables
    Current table_definition_cache = 1400 tables
    You have a total of 113 tables
    You have 117 open tables.
    The table_cache value seems to be fine
    
    TEMP TABLES
    Current max_heap_table_size = 16 M
    Current tmp_table_size = 16 M
    Of 1072 temp tables, 6% were created on disk
    Created disk tmp tables ratio seems fine
    
    TABLE SCANS
    Current read_buffer_size = 128 K
    Current table scan ratio = 440 : 1
    read_buffer_size seems to be fine
    
    TABLE LOCKING
    Current Lock Wait ratio = 0 : 1168
    Your table locking seems to be fine
