ayarlar sizce nasıl bazen asırı yuklenmeler oluyor, table cache arttırdıkca daha fazla arttırmalısın diyor bu normalmi dahada arttırmalımıyım

SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 3 sec.
You have 214 out of 9684681 that take longer than 3 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 MySQL :: MySQL 5.0 Reference Manual :: 6.3 Point-in-Time Recovery

WORKER THREADS
Current thread_cache_size = 32
Current threads_cached = 31
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 800
Current threads_connected = 165
Historic max_used_connections = 261
The number of used connections is 32% of the configured maximum.
Your max_connections variable seems to be fine.

MEMORY USAGE
Max Memory Ever Allocated : 2 G
Configured Max Per-thread Buffers : 6 G
Configured Max Global Buffers : 138 M
Configured Max Memory Limit : 6 G
Physical Memory : 15.70 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 69 M
Current key_buffer_size = 128 M
Key cache miss rate is 1 : 968
Key buffer fill ratio = 5.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is supported but not enabled
Perhaps you should set the query_cache_size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 1 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 2.00 M
You have had 2663 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 = 50810 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 = 25000 tables
You have a total of 4626 tables
You have 25000 open tables.
Current table_cache hit rate is 50%, 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 56978 temp tables, 2% 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 = 1 M
Current table scan ratio = 239 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 4238
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'.
