SLOW QUERIES
Current long_query_time = 10 sec.
You have 1 out of 115180 that take longer than 10 sec. to complete
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.

WORKER THREADS
Current thread_cache_size = 16
Current threads_cached = 4
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 768
Current threads_connected = 7
Historic max_used_connections = 11
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

MEMORY USAGE
Max Memory Ever Allocated : 833 M
Configured Max Per-thread Buffers : 25 G
Configured Max Global Buffers : 458 M
Configured Max Memory Limit : 26 G
Physical Memory : 3.95 G

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 77 M
Current key_buffer_size = 384 M
Key cache miss rate is 1 : 75
Key buffer fill ratio = 1.00 %
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 = 64 M
Current query_cache_used = 11 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 18.33 %
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 = 6 M
Current record/read_rnd_buffer_size = 15 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 8.00 M
You have had 0 queries where a join could not use an index properly
Your joins seem to be using indexes properly
join_buffer_size >= 4 M
This is not advised

OPEN FILES LIMIT
Current open_files_limit = 65535 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_cache value = 2048 tables
You have a total of 4893 tables
You have 2048 open tables.
Current table_cache hit rate is 10%, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 381 temp tables, 16% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 3 M
Current table scan ratio = 73 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 0 : 115483
Your table locking seems to be fine
