SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 2258 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

WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 3
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 1000
Current threads_connected = 3
Historic max_used_connections = 6
The number of used connections is 0% 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
No InnoDB Support Enabled!
MEMORY USAGE
Max Memory Ever Allocated : 4.76 G
Configured Max Per-thread Buffers : 625.48 G
Configured Max Global Buffers : 1.01 G
Configured Max Memory Limit : 626.50 G
Physical Memory : 7.92 G
Max memory limit exceeds 90% of physical memory
KEY BUFFER
Current MyISAM index space = 35 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 221
Key buffer free ratio = 73 %
Your key_buffer_size seems to be fine
QUERY CACHE
Query cache is enabled
Current query_cache_size = 1.00 G
Current query_cache_used = 8 K
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 0 %
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 = 512 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 3 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 = 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 = 64 tables
Current table_definition_cache = 256 tables
You have a total of 867 tables
You have 64 open tables.
Current table_cache hit rate is 6%
, 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 = 16 M
Current tmp_table_size = 1.00 G
Of 387 temp tables, 25% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.
TABLE SCANS
Current read_buffer_size = 128 M
Current table scan ratio = 364 : 1
read_buffer_size is over 8 MB there is probably no need for such a large read_buffer
TABLE LOCKING
Current Lock Wait ratio = 1 : 2487
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=2'.
