mempercepat koneksi internet ubuntu

kadang saat modem sudah konek lalu kita buka browser tetapi kebanyakan tidak jalan dan kita harus tutup browser lagi, ini sedikit trik supaya koneksi ubuntu lebih cepat.
ini telah saya coba diubuntu 14.04 dan hasilnya work 100%.
oke kita ketkp saja :D

buka terminal :

sudo gedit /etc/sysctl.conf

ini akan membuka sistem networking berupa gedit/scrips,lalu copy scrips dibawah ini:

# 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

lalu klik clt + s (save) dan tutup gedit

untuk mengaktifkan setting scrips yang kita buat,copy scrips ini diterminal:

sudo sysctl -p

semoga bermanfaat bigi teman yang mampir kesini
