there are some nice charts at the below link showing the quickness of
the new iphone... enjoy...

In loading a series of complex websites over Wi-Fi, AnandTech has found
that the 3G S is about 54 percent faster on average than the 3G and, in
a few cases, is about three times faster. But it's also about 11 percent
faster than the Palm Pre, which shares WebKit as a rendering engine, and
is only slower in two out of nine tests. That lead only grows wider with
the T-Mobile G1: as it's slower than the iPhone 3G, it's often twice as
fast or more.

Load times for commonly available apps were less dramatic between
iPhones but only exacerbated the gaps between the Pre and Apple's
hardware. A 3G S is between 13 percent and 42 percent faster at loading
these apps versus a 3G depending on conditions, but it starts these
roughly between two and four times faster than a Pre. Again, the sole
Android phone in the comparison is slower still in all but Google Maps.

Almost all of the speedup is attributed to the Samsung ARM Cortex A8
processor at the heart of the new iPhone. Its clock speed gain is
obvious, but it can also issue two instructions at once instead of the
original iPhone's one and has more than twice as much cache. Palm is
using an OMAP 3 chip from Texas Instruments that itself is considered
fast.
