I must admit, it looks a bit geeky. I have had a close look at the main site and forum and can't really decide what sort of increase in speed you're suposed to expect, probably a difficult question to be fair.
Looking at the program, it looks like you're likely to spend a lot of time tweaking and worrying about that little extra speed, you may or may not obtain, than enjoying your surfing.
Personally, I think I'll leave alone because I think my connection is as good as it gets without worrying about an extra 1Kb/s download speed. Thanks for the interesting site anyway. I would be interested on other peoples views as well.
If you are having problems with download speeds the people to contact are your telephone system providers to get them to try and increase the gain or whatever on the telephone line, not by stuffing your computer with useless software. No amount of magic programs can improve your connection speed to anything better than the system can provide. If this is at a maximum that it the best you can get.
