นี่ครับ my.cnf ram 16 gb
CentOS6.0+Mysql 5.1.45-51
ผมแนะนำว่าถ้าจะให้ระบบไหลลื่นกว่านี้น่าจะ
CentOS-6.4+ MySQL-5.5.30 หรือ CentOS-6.4+ MySQL-5.6.10
รับรองว่าเร็วกว่า Percona-Server-5.5.xx แน่นอน
ถ้าเป็น MySQL-5.5.xx or MySQL-5.6.xx โทรมาติดต่อนะครับ
สำหรับ my.cnf ที่แก้ไข สามารถ วางแล้ว รัน mysql ได้เลย โดยไม่ต้องลง linux ใหม่
