em dùng con router 2811 với 2 đường FTTH với bandwith trung bình là 16mb/s upload và 3mb/s download thì thấy cpu lên tới 50% mà kỳ nhất là em show proces cpu lên cộng đi cộng lại cũng không tới 10%
Vậy có tiến trình background nào không và show lên như thế nào ?
Vì em thầy khi bandwidth càng cao thì cpu lên càng nhiều
khi ban đêm thì bandwith trung bình là 2mb/s upload và 0,3 mb/s download thì cpu chỉ khoảng 8%
khi ban ngày khi bandwith tổng cộng 2 đường tăng thì cpu tăng lên theo
Em không biết là cpu 50% khi xử lý băng thông như vậy là bình thường không ?
Hay em cấu hình gì sai

Vậy có tiến trình background nào không và show lên như thế nào ?
Vì em thầy khi bandwidth càng cao thì cpu lên càng nhiều
khi ban đêm thì bandwith trung bình là 2mb/s upload và 0,3 mb/s download thì cpu chỉ khoảng 8%
khi ban ngày khi bandwith tổng cộng 2 đường tăng thì cpu tăng lên theo
Em không biết là cpu 50% khi xử lý băng thông như vậy là bình thường không ?
Hay em cấu hình gì sai
