25-30klık tekil hite sahip wordpress üzerine kurulu sitem var.. akşam 9-12 arası load avarega 70 e kadar fırlıyor.mysqla restart atınca toparlıyor yarım saat geçmeden yine kapanıyor..puttyle baglanırken bile zorlanıyorum bu durumda..bandwithd %70 i resimlerden gidiyor..
makinanın özellikleri ;
OS: CentOS 5.xHardware: Intel Core 2 Duo 2.66/1024MB/250GB

1.sorum böle bi makinanın 70binlık tekil hiti kadar karşılaması gerekmezmi ?
2.1gblık ram eklettirdim.. daha başka bişe yapmalımıyım ?
3.Zend Optimizer,apf,sim v.s. gibi programlar kurmalımıyım ? (bu programlara gerek yok my.cnf v.s. gibi küçük ayarlar dahamı uygun olur.. )
4.tekil hit 100k lık siteyi karşılamak için 1-2 makina dahamı almalıyım..
5.resimlerin boyutlarıyla oynasam çok fark olurmu gerek yokmu..?

1 gblık ram taktırdım şimdilik load avarage 5in üstüne çıkmadı.. %80i bile gormuştum.. my.cnf ayarı kaldı halen ugraşmaktayım..

Adım adım cevap vereyim,


1) optimize olmayan bir 5558555 işlemcili sunucuda olsa 100K zor..
2) extra ram her zaman işine yaramıştır Linux sistemlerin doğru adım atmışsınız.
3) apf, csf tarzı programlar sunucundaki performansı yakından etkilemeyecektir. Optimizer veya Cacher kurarsan (xCache, Zend vb) elbette yardımcı olacaktır.
4) Bu sunucuya 4GB ram ve sağlam bir optimize ile 100K kaldırtabilirsin
5) resimlerin boyutuyla oynarsan sadece kullanacağın band limiti değişir..

SLOW QUERIES
Current long_query_time = 10 sec.
You have 0 out of 1735794 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 = 0
Current threads_cached = 0
Current threads_per_sec = 10
Historic threads_per_sec = 7
Threads created per/sec are overrunning threads cached
You should raise thread_cache_size
MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 2
Historic max_used_connections = 31
The number of used connections is 31% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 101 M
Configured Max Per-thread Buffers : 268 M
Configured Max Global Buffers : 17 M
Configured Max Memory Limit : 286 M
Physical Memory : 2.96 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 1 M
Current key_buffer_size = 7 M
Key cache miss rate is 1 : 1094
Key buffer fill ratio = 4.00 %
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 record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 0 queries where a join could not use an index properly
Your joins seem to be using indexes properly
OPEN FILES LIMIT
Current open_files_limit = 1024 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 = 64 tables
You have a total of 302 tables
You have 64 open tables.
Current table_cache hit rate is 17%, 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 20126 temp tables, 44% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
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 impact your
ratio of on disk temp tables.
TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 3 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 801435
Your table locking seems to be fine

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.
