Bandwidth Monitor

Bandwidth Monitor is a software tool that was developed in Java so as to help you keep track of your bandwidth usage in your network.

Use it on any PC

This utility happens to be portable and therefore, the installation process can be easily skipped. Consequently, you can copy the program files to a USB flash drive or other similar external data device, so as to take it everywhere with you and quickly run it on any machine, without worrying about the installation.
Another aspect that you should take into consideration is that Bandwidth Monitor is not going to create new entries in the Windows registry, and thus, there will be no leftovers after its removal.

Clean environment

The UI you come face to face with boasts a pretty uncomplicated and straightforward design, as it only consists of a small menu bar, and a panel to display the network usage. It is suitable to all user categories, even those with little to no previous experience with computers.

Choose a network and keep track of the download and upload speed

This software utility can detect all your network connections, and enables you to select one of them in order to begin monitoring it.
Once you have completed this action, a graphical representation of the bandwidth usage is going to be displayed in the main window. It is possible to view the download and upload speed every few seconds, and you should know a color-coded system is in place.
CPU and memory usage is moderate to high, which means that it might affect, from time to time, the way in which your computer runs. That is why it is a good idea not to run it alongside other demanding apps.

Conclusion

Taking all of this into consideration, we can safely say Bandwidth Monitor is an efficient piece of software. The response time is good and the interface is accessible to everybody. Nonetheless, the lack of options might ward off power users.
