- Bir onceki mesajimda bahsettigim
set-variable=local-infile=0
satirini my.cnf den kaldir.
- Bunlari eski degerine getir:
key_buffer=64M #eskideğer-32M
query_cache_size=64M #eskideğer-32M
- Innodb icin asagidaki ayarlari ekle
innodb_buffer_pool_size=32M
innodb_additional_mem_pool_size=16M
innodb_thread_concurrency=8
innodb_flush_method=O_DIRECT
PHP ye kurulu degilse Xcache yada eAccelerator kur.

iyinet: tavsiyelerinden 2 gün sonra aldığım rapora göre sonuçlar aşağıda.
Anladığım kadarıyla, key_buffer değerini azaltıp, zend'i kaldırıp xcache veya eaccelerator kurmak harici yapılacak birşey kalmıyor değil mi ?

-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 5.0.54 i686
Uptime = 2 days 1 hrs 5 min 19 sec
Avg. qps = 67
Total Questions = 11966357
Threads Connected = 1
Server has been running for over 48hrs.
It should be safe to follow these recommendations
To find out more information on how each of these
runtime variables effects performance visit:
http://dev.mysql.com/doc/refman/5.0/...variables.html
Visit http://www.mysql.com/products/enterprise/advisors.html
for info about MySQL's Enterprise Monitoring and Advisory Service
SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 4 sec.
You have 12 out of 11966487 that take longer than 4 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 http://dev.mysql.com/doc/refman/5.0/...-recovery.html
WORKER THREADS
Current thread_cache_size = 256
Current threads_cached = 91
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 = 1
Historic max_used_connections = 92
The number of used connections is 46% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 360 M
Configured Max Per-thread Buffers : 537 M
Configured Max Global Buffers : 113 M
Configured Max Memory Limit : 650 M
Physical Memory : 1.97 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 9 M
Current key_buffer_size = 32 M
Key cache miss rate is 1 : 12575
Key buffer fill ratio = 25.00 %
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 = 32 M
Current query_cache_used = 20 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 63.22 %
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 read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 1 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 = 1234 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 = 512 tables
You have a total of 162 tables
You have 307 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 47725 temp tables, 1% 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 = 128 K
Current table scan ratio = 3459 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 4531
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'.
