Merhaba, ssh de çalıştırabileceğiniz bu script mysql ayarlarınızı kontrol edip tavsiyede bulunuyor.

teşekkürler, ...

Teşekkürler iyinet. MySQL optimizasyonu konusunda gayet yararlı bilgiler veriyor. Buradaki önerilere göre MySQL'i optimize etmeniz sitenizin açılış hızını kat ve kat artıracaktır.

385 mi yoksa 512 mi karar verin

TABLE CACHE Current table_cache value = 64 tables You have a total of 385 tables You have 64 open tables. Current table_cache hit rate is 0%, while 100% of your table cache is in use You should probably increase your table_cache

teşekkürler iyinet.

mysql optimizastonu için tuning-primer. sh scriptini indirmenizi öneririm. ssh de çalıştırabileceğiniz bu script mysql ayarlarınızı kontrol edip tavsiyede bulunuyor. scriptin adı: tuning-primer. sh scriptin bulunduğu site: http://day32.com/MySQL/ doğrudan link: http://day32.com/MySQL/tuning-primer. sh ssh de çalıştırmak için: # wget http://day32.com/MySQL/tuning-primer. sh # chmod u+x tuning-primer. sh # ./tuning-primer. sh

Tamamdir tesekkurler arkadaslar Konu optimizasyondan acilmisken deyinmek istiyorum. benim serverda veriler cok hizli geliyor şak diye ekranda oluyor ancak grafiklerin ekrana gelişi cok zaman aliyor boyutlari gercekten cok kucuk olmalarina ragmen boyle. Bununla ilgili bir onerisi olan varmi?

my. cnf içindeki table_cache değerini 385 yap, yoksa ekle: table_cache = 385
