Between the time you click a link and a web page finishes loading on your iPhone, there are many factors that ultimately decide just how fast that process will be, including connection speed (2.5 G EDGE/3G HSDPA/WiFi) CPU speed, and rendering engine. Like desktop Safari, Mobile Safari uses Apple’s open source WebKit rendering engine, and it seems like for 2.0, WebKit has gotten its turbo on, especially in handling Javascript. Says Daring Fireball:

For all the hubbub regarding the new App Store, most “iPhone software” runs in the web browser. But improvements in WebKit performance often help native iPhone app performance, too — a slew of my favorite native iPhone apps have built-in WebKit browsers (e.g., NetNewsWire, Twitterrific, Instapaper, and Cocktails). When WebKit performance improves, any app that uses WebKit improves, and WebKit improved a lot between iPhone 1.1.4 and 2.0.0

The original iPhone on 1.0 was already fast compared to some 3G phones because of the speed of its CPU and the optimization of its WebKit engine. Now it’s getting silly fast. And I don’t think we’ve even gotten the extra nitro from the new Safari 4 and SquirelFish tech yet either?

Just prior to the original iPhone’s release, AT&T’s operation “Fine Edge” brought faster, stronger, better 2.5 / 2.75G speed to the GSM masses. This year, in a strangely reminiscent move, reports are coming in that AT&T is showing their 3G HSPA network the same type of love:

For the past few months we’ve been seeing average download speeds between 500 – 800 kbps with a spike here and there. This morning’s tests however, are yielding between 1400 – 1500 kbps.

Gee, could another iPhone release be on the horizon?

Despite the iPhone’s Mobile Safari browser rendering pages faster on Edge than many “competing” devices can on lesser browsers with faster connections, the race to speed the feeds continues, and AT&T has not only taken an early lead, but is positively driving towards the 3G finish-line.

Amazing what a little technology (and a billion dollars) can do.

WMExperts.com cites a recent survey where AT&T’s HSDPA trounced EVDO Rev A., averaging 755kbps with bursts peaking at 1.6mbps(!)

In Apple-parlance: It’s a screamer.

But wait, there’s more: AT&T intends to increase its network speed by a factor of 5 by next year. That’s a quintuple screamer right there, never mind the upcoming switch to 4G LTE speeds…
