From the interface we will be able to control and know the upload and download state through full featured statistics which are stored in a database, so we will be able to consult all the information since the program was installed.
Thanks to Bitmeter II, after a pair of months we will have a detailed database of our internet connection. It is specially focussed on broadband users.
It is fully customizable and we will be able to setup alarms, when the speed falls below a certain speed.
In short, it is a very useful tool which consumes few resources and it is totally free.
