Mempercepat koneksi Internet di linux Ubuntu 10.10

Pada tutorial kali inni saya akan membahas cara mempercepat koneksi internet di linux dengan mengoptimalkan konfigurasi sysctl, ok langsung saja :
1. Buka Terminal atau Konsole

– Buat backup file sysctl.conf yang kita edit :

$ sudo cp /etc/sysctl.conf /etc/sysctl.conf.backup

– Edit file tersebut :

$ sudo gedit /etc/sysctl.conf

– Copy kode di bawah dan masukan ke baris kode akhir file yang kitaedit :

# increase TCP max buffer size setable using setsockopt(

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

# increase Linux autotuning TCP buffer limits

# min, default, and max number of bytes to use

# set max to at least 4MB, or higher if you use very high BDP paths

net.ipv4.tcp_rmem = 4096 87380 16777216

net.ipv4.tcp_wmem = 4096 65536 16777216

# don’t cache ssthresh from previous connectionnet.ipv4.tcp_no_metrics_save = 1

net.ipv4.tcp_moderate_rcvbuf = 1

# recommended to increase this for 1000 BT or higher

net.core.netdev_max_backlog = 2500

# for 10 GigE, use this, uncomment below

# net.core.netdev_max_backlog = 30000

# Turn off timestamps if you’re on a gigabit or very busy network

# Having it off is one less thing the IP stack needs to work on

#net.ipv4.tcp_timestamps = 0

# disable tcp selective acknowledgements.

net.ipv4.tcp_sack = 0

#enable window scaling

net.ipv4.tcp_window_scaling = 1

– Simpan file

– Ketikan untuk menjalankan file yang telah kita edit

$ sudo sysctl -p
