Trik mempercepat koneksi internet di Ubuntu


Ada sedikit trik nih buat mempercepat koneksi internet di Ubuntu. Sistem kerjanya yaitu mengoptimalkan kecepatan reload data saat kita berinternet. Jadinya nanti di browser akan terasa lebih cepat memunculkan halaman. Silahkan di review sendiri-sendiri deh ya. :D kalo di mesin saya sih trik ini lumayan kerasa. :D

Yuk langsung aja, berikut cara-caranya :

1. Buka terminal, lalu ketikkan perintah berikut :

sudo gedit /etc/sysctl.conf

2. Lalu kopikan skrip berikut di baris paling bawah :

# 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



Save (CTRL + S) lalu keluar.

3. Aktifkan settingan diatas dengan cara ketik :

sudo sysctl -p

Semoga bermanfaat :)
