Cara Mempercepat Koneksi Internet Di Ubuntu 12.04 LTS

Cara Mempercepat Koneksi Internet Di Ubuntu 12.04 LTS - Di Indonesia yang namanya koneksi internet, kalau pengen kenceng, harus berani bayar dengan harga lebih. nah bagi kantong mahasiswa hanya mampu menjangkau koneksi internet yang speednya kayak siput. oy kali ini saya akan membagikan tutorial tang KATANYA ampuh untuk mempercepat koneksi internet, tapi ini khusus Ubuntu dan keturunannya.

Caranya sbb :
1. Open terminal - Ctrl+Alt+T
2. Ketikkan perintah berikut di terminal :

sudo gedit /etc/sysctl.conf

3. Akan muncul halaman dokumen, lalu copy-paste perintah-perintah berikut ini di baris paling akhir :

# 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 connection
net.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

4. Save dokumennya lalu keluar.
5. Ketikkan perintah berikut di terminall untuk melakukan apply :

sudo sysctl -p

hasilnya:

net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_moderate_rcvbuf = 1
net.core.netdev_max_backlog = 2500
net.ipv4.tcp_sack = 0
net.ipv4.tcp_window_scaling = 1

6. Selesai :)
