_ Mở Đầu:

Em đang triển khai dịch vụ squid proxy và trong quá trình tuning để đạt hiệu suất cao cho squid . Hiện còn nhiều thiếu xót mong anh em có thể góp y giúp mình nha .

_ Thông Tin:
CPU : Xeon E504 2Ghz
Ram : 4GB
HDD : Sata WD 150GB ( 8Gb Swap & 100Gb / )
OS : CentOS 5.8
Squid Proxy : V2.6

Mình cấu hình mong muốn đáp ứng được cho khoản 600 user

_ Tình Trạng
_ Tốc độ không cao
_ Load trang chủ hơi chậm ( các trang con nhanh hơn )

_ Squid.conf
