başınızı çok agırtıyorum ama bu işaretledigim yedeki değer 8 gün için normal mi acaba, bunu artması bi sorun oluşturur mu.
gönderdiğim bilgilerde tablolarla ilgili birçok şey yer alıyor. Yazılım ile ilgili bir sıkıntı yok çünkü diğer sunucularda da aynı yazılım çalışıyor ama bu makine kasılıyor.
gönderdiğim bilgileri bi gözden geçirip önerinizi alabilirsem mutlu olurum.. xcache kuramıyorum çünkü zend optmizer 3.3 kullanıyorum.. bunun dışında eacceloator gibi bi uygulamadan bahsediliyor falkat veriminden yada dezavantajından kimse bahsetmemiş..

SLOW QUERIES
Current long_query_time = 10 sec.
You have 3 out of 369639 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 = 384
Current threads_cached = 21
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 = 8
Historic max_used_connections = 25
The number of used connections is 5% 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 : 264 M
Configured Max Per-thread Buffers : 2 G
Configured Max Global Buffers : 154 M
Configured Max Memory Limit : 2 G
Physical Memory : 3.95 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 825 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 275
Key buffer fill ratio = 100.00 %
You could increase key_buffer_size
It is safe to raise this up to 1/4 of total system memory;
assuming this is a dedicated database server.
QUERY CACHE
Query cache is enabled
Current query_cache_size = 128 M
Current query_cache_used = 36 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 28.47 %
Current query_cache_min_res_unit = 4 K
Query Cache is 16 % 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 = 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 9 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 = 4110 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 = 1800 tables
You have a total of 338 tables
You have 396 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 13933 temp tables, 3% 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 = 1417 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 176
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'

Sanırım uptime vakti doldu. Bu değerlere uygun bir yapılandırma yazarsanız sevinirim. Load 4 - 6 arası dolanıyor. xcache kurmak istiyorum ama serverda zend var. Zendi kaldırıp xcache kurunca mesaj gönderiminde hata oluşuyor. Boş bir sayfa çıkıyor karşıma. Error yada bekleme yok. Bu yüzden Loadı düşüremedim.
mysqld altındaki var olan ayarları bu şekilde değiştirin, ayar yoksa ekleyin.
