Faster internet broadband tweak


Stabilise and increase your broadband internet speed with this tweak.

This tweak is quite well known. It involves adding some lines into /etc/sysctl.conf

You can add/change quite a number of things, but the ones that made the most difference were these;

/etc/sysctl.conf

# add these lines..

# Speed Teaks
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_rmem = 4096 65536 16777216

net.ipv4.tcp_wmem = 4096 65536 16777216

net.ipv4.tcp_window_scaling = 1

net.ipv4.tcp_sack = 1
# End Speed Tweaks

The last line (net.ipv4.tcp_sack = 1) is quite important. Some users turn this off, but for me, it causes instability (throughput suddenly pauses in the middle of a download) so I leave it on.

And here is an example of a test at  https://comparite.ch/speed
