SLOW QUERIES
Current long_query_time = 3 sec.
You have 2127 out of 177576987 that take longer than 3 sec. to complete
The slow query log is enabled.
Your long_query_time seems to be fine
WORKER THREADS
Current thread_cache_size = 286
Current threads_cached = 89
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 = 92
The number of used connections is 9% 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 : 1 G
Configured Max Per-thread Buffers : 7 G
Configured Max Global Buffers : 353 M
Configured Max Memory Limit : 7 G
Physical Memory : 1.94 G
Max memory limit exceeds 90% of physical memory
KEY BUFFER
Current MyISAM index space = 125 M
Current key_buffer_size = 128 M
Key cache miss rate is 1 : 586
Key buffer fill ratio = 34.00 %
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 = 128 M
Current query_cache_used = 90 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 70.58 %
Current query_cache_min_res_unit = 4 K
Query Cache is 12 % 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.
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 3 M
Current record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 2.00 M
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_cache value = 1024 tables
You have a total of 236 tables
You have 209 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 64 M
Of 210323 temp tables, 76% 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 = 1 M
Current table scan ratio = 20 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 7018
Your table locking seems to be finemysqltuner.pl sonucu:>> MySQL High-Performance Tuning Script - Major Hayden <major@mhtx.net>

-------- Recommendations -----------------------------------------------------
General recommendations:
Be sure that tmp_table_size/max_heap_table_size are equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
*** MySQL's maximum memory usage exceeds your installed memory ***
*** Add more RAM before increasing any MySQL buffer variables ***
query_cache_size (> 128M)
tmp_table_size (> 64M)
max_heap_table_size (> 16M)
table_cache (> 1024)
