cFosSpeed really does the job?

Hi everyone. It's been almost 2 years since I've being using cFosSpeed software (Traffic Shaping) Through this years I notice that I can do more stuff at a same time (videos, online games, etc) without having a major impact on each one. The thing is... My internet speed it's only 2 mb down and 768kb up. And I would really like to know if you could put this piece of software at a real test to see if the program really does something or if it's just my idea on being faster. And maybe your opinion on getting a better experience online it's on faster internet speeds?

The link of the program it's: http://www.cfos.de/en/cfosspeed/cfosspeed.htm
