Yes I believe this tool just clears up me memory to make your connection faster but like I said it doesn't work for everybody. Also I downloaded this clean up utility called SmartClose it does just make your computer faster but closing unused programs but to me helps clear up space for my internet to run faster.
Also if you have FF you can download the Fasterfox add on. It doesn't really help for download speeds but for just surfing to pages just makes it faster.
