I'm assuming you're talking about internet on the phone.
That said, that mostly depends on your connection lol. The better the connection the "faster" the internet is. Although OC'ing your processor comes in handy for pages load faster too. Stock 2.2 is at around 600-800mhz, I think 800...so it's already going to be faster if you're just stock 2.1.
Hope that helped...I'd suggest just go for the leap, if you don't like it, go back lol.
