	-- MYSQL PERFORMANCE TUNING PRIMER --
	     - By: Matthew Montgomery -

MySQL Version 5.5.54-0+deb8u1 x86_64

Uptime = 0 days 23 hrs 50 min 29 sec
Avg. qps = 1008
Total Questions = 86520974
Threads Connected = 804

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 3 out of 86521947 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/5.5/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 1
Historic threads_per_sec = 16
Threads created per/sec are overrunning threads cached
You should raise thread_cache_size

MAX CONNECTIONS
Current max_connections = 15000
Current threads_connected = 804
Historic max_used_connections = 1011
The number of used connections is 6% 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 = 192 K
Current InnoDB data space = 73 M
Current InnoDB buffer pool free = 40 %
Current innodb_buffer_pool_size = 128 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 : 34.97 G
Configured Max Per-thread Buffers : 479.73 G
Configured Max Global Buffers : 2.64 G
Configured Max Memory Limit : 482.37 G
Physical Memory : 47.26 G

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 165 M
Current key_buffer_size = 2.00 G
Key cache miss rate is 1 : 19705
Key buffer free ratio = 77 %
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 = 512 M
Current query_cache_used = 33 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 6.45 %
Current query_cache_min_res_unit = 4 K
Query Cache is 22 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
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 = 32 M
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 132.00 K
You have had 18757 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 = 75000 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 = 1024 tables
Current table_definition_cache = 400 tables
You have a total of 926 tables
You have 1024 open tables.
Current table_cache hit rate is 87%
, while 100% of your table cache is in use
You should probably increase your table_cache
You should probably increase your table_definition_cache value.

TEMP TABLES
Current max_heap_table_size = 128 M
Current tmp_table_size = 128 M
Of 35546 temp tables, 12% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 420 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 260
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'.
