Yardımcı olursanız çok memnun olurum. Bazı noktalarda kırmızı olan bölümler var. Daha iyi bi sonuç için neleri değiştirmemi önerirsiniz.

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

MySQL Version 4.1.22-standard i686

Uptime = 9 days 8 hrs 18 min 37 sec
Avg. qps = 0
Total Questions = 323246597
Threads Connected = 16

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

runtime variables effects performance visit:

SLOW QUERIES
Current long_query_time = 10 sec.
You have 1474 out of 323246610 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 = 256
Current threads_cached = 103
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 15
Historic max_used_connections = 118
The number of used connections is 23% of the configured maximum.
Your max_connections variable seems to be fine.

MEMORY USAGE
Max Memory Ever Allocated : 842 M
Configured Max Per-thread Buffers : 2 G
Configured Max Global Buffers : 202 M
Configured Max Memory Limit : 2 G
Physical Memory : 1.97 G

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 119 M
Current key_buffer_size = 64 M
Key cache miss rate is 1 : 19065
Key buffer fill ratio = 76.00 %
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 = 82 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 64.26 %
Current query_cache_min_res_unit = 4 K
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 1.00 M
You have had 163 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 = 8702 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
You currently have open more than 75% of your open_files_limit
You should set a higher value for open_files_limit in my.cnf

TABLE CACHE
Current table_cache value = 4096 tables
You have a total of 11247 tables
You have 4096 open tables.
Current table_cache hit rate is 12%, while 100% of your table ca
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 252234 temp tables, 35% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_
Perhaps you should increase your tmp_table_size and/or max_heap_
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 im
ratio of on disk temp tables.

TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 53 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 4085
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perf
frequent updates consider setting 'low_priority_updates=1'
