Buka Terminal : (ctrl+alt+T) : menu > administration > terminal
</div>-
backup dulu file sysctl.conf, caranya “sudo cp /etc/sysctl.conf /etc/sysctl.conf.backup” (tanpa petik), jadi kalo ada eror hasil backupannya di sysctl.conf.backup
</div>-
edit file sysctl.conf : “sudo gedit /etc/sysctl.conf” (tanpa petik) untuk editornya bisa make nano, gedit, leafpad/dll
</div>-
tambahin kode ajaib ini di akhir file yang di edit tadi :
—————————————————————————————————————# 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
