Internet surfing is slow?

I need to find a fix to this, my internet itself is really fast. Just surfing is slow. I do registry cleans, defrag, reboot.. everything. My computer is fast overall too. I've tried almost all the browsers there are (Firefox, IE, Opera, etc) and it still goes slow. Like I said, my internet itself is fast and so is my computer, but browsing is slow. Any ideas why or how could I fix this?
