Optimize your Internet connection (TCP) and maximize your bandwidth in Linux
Simply modify your sysctl file and poof!
sudo gedit /etc/sysctl.conf
copy and past the following code at the last line on your sysctl file
# 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
tada… now run the following command
sudo sysctl -p
