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

MySQL Version 5.0.45-community-log i686

Uptime = 2 days 8 hrs 22 min 46 sec
Avg. qps = 105
Total Questions = 21453510
Threads Connected = 7

Server has been running for over 48hrs.
It should be safe to follow these recommendations

SLOW QUERIES
Current long_query_time = 3 sec.
You have 1714 out of 21453608 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 = 384
Current threads_cached = 122
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 200
Current threads_connected = 2
Historic max_used_connections = 124
The number of used connections is 62% of the configured maximum.
Your max_connections variable seems to be fine.

MEMORY USAGE
Max Memory Ever Allocated : 847 M
Configured Max Per-thread Buffers : 835 M
Configured Max Global Buffers : 330 M
Configured Max Memory Limit : 1 G
Physical Memory : 3.90 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 847 M
Current key_buffer_size = 256 M
Key cache miss rate is 1 : 4972
Key buffer fill ratio = 74.00 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 64 M
Current query_cache_used = 52 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 82.55 %
Current query_cache_min_res_unit = 4 K
Query Cache is 10 % 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.
However, 255895 queries have been removed from the query cache due to lack of memory
Perhaps you should raise query_cache_size
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 1 M
Current record/read_rnd_buffer_size = 1020 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 1.00 M
You have had 2608 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 = 20210 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 = 10000 tables
You have a total of 4518 tables
You have 9165 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 692430 temp tables, 7% 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 = 1020 K
Current table scan ratio = 293 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 1092
You may benefit from selective use of InnoDB.
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.

Son durum bu. Yorumlarsanız çok sevinirim sayın iyinet
Saygılar.
