        -- MYSQL PERFORMANCE TUNING PRIMER --

MySQL Version 5.6.27 x86_64

Uptime = 0 days 2 hrs 48 min 22 sec
Avg. qps = 0

Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations

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
