					Langkah Mudah Meningkatkan Kecepatan Koneksi Internet Pada Ubuntu/Linux

memaksimalkan kecepatan koneksi internet Anda dengan sysctl.conf :

1. Buka Terminal : Application -> Accessories -> Terminal
2. Buka file sysclt.conf dengan cara ketik :
sudo gedit /etc/sysctl.conf

3. Copy teks dibawah ini lalu pastekan pada baris terakhir sysctl.conf

# 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. Simpan hasil editan diatas dengan cara tekan keyboard Ctrl + S, kemudian tekan Alt + F4 untuk
keluar

5. Aktifkan settingan diatas dengan cara ketik :

sudo sysctl -p

Untuk menonaktifkan settingan diatas, hapus semua baris seperti pada langkah ke 2 di sysctl.conf,
ketik :

sudo gedit /etc/sysctl.conf
