Increase your internet speed with Namebench

NameBench is a program that searches for the fastest DNS in your area. After the program is finished searching and comparing between DNS it will give you the results including the fastest and nearest DNS in your area. After that all you have to do is edit your connection settings to use the fastest DNS available. NameBench is available for Windows and Mac systems, but most importantly it is Linux compatible.
Prepare your system

Install following package

sudo apt-get install python-tk

Now you need to download .tgz file from here

Now extract the file using the following command

tar xzvf namebench-1.1.tgz

Now you have namebench-1.1 directory.If you double click on this you have two options if you want to run immediately you can do by double clicking on namebench.py file.

If you want to install permanently using the following command

sudo python setup.py install

Once it opens you should see similar to the following screen here click on Start Benchmark



The results are compared to Google’s DNS and the system will compare against your current DNS settings. The fastest DNS will be listed at the top.

How to increase internet speed in ubuntu

Internet speeds in Ubuntu can be increased. Simply follow the steps.

Open a Terminal via Applications->Accessories->Terminal and type the following

sudo vim /etc/sysctl.conf (press i for edit mode)

Then Paste the Following at the end of the 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



Then type the follwing to exit and save what you have just done. Press ESC to quit the edit mode and type the following.

:wq

Then type the following to to apply the settings.

sudo sysctl -p

You can disable all these settings by removing these lines you added via:

sudo gedit /etc/sysctl.conf
