Merhaba Arkadaşlar,

MySQL ayarlarımı gözden geçirmeye karar verdim. Kendim bazı düzenlemeler & ayarlar yaptım ama sizlerin de görüşüne başvurmak isterim.

Harddisk: 2x 2000 GB SATA 3,5" 7.200 rpm
CPU: AMD Opteron 3280 Octacore
Barebone: Fujitsu PRIMERGY MX130 S2
RAM: 24x Gigabyte RAM

PHP 5.4
Apache 2.2.26
Memcached
APC
