Here's what I had to say on the topic in another post (I got no replies):
I think speed tests and download performance are interesting issues. I get 25MB on my wired desktop PC and about 18-20MB on PCs receiving wifi. I downloaded the speedtest.net app to my iPad and it shows that I get 15MB. I don't know if the the dslreports.com iPhone browser speed test is supposed to used on the iPad or is considered to be reliable, but using it I get about 3MB. Using the dslreports.com test on my iPhone, I get about 1.5MB.
Here's where I'm coming from, and here's my experience: I really like my iPad, and don't have any axe to grind with Apple or anybody else. However, regardless of any speed test result and regardless of all this router mumbo jumbo, there is no way on earth that web pages download as fast on the iPad as they do on my wifi computers. The 15MB that I get from the speedtest.net app is way out of whack with reality. For example, NYTimes.com downloads on my wifi connected laptop essentially instantly, like changing the channel on a TV. The same web page takes about 10 seconds to download on my iPad. This despite the 15MB result from the speedtest.net app. I think the speedtest.net app is simply wrong, even though I've always heard that you don't get false positives from any speed test; or, the speedtest.net app is measuring something that isn't relevant to the speed of web browsing. In my non-techie view, the dslreports.com test results are a more meaningful and accurate measurement.
In other words, the speed of web browsing on the iPad is a lot closer to the speeds you get on a smart phone rather than the speeds you get on a wifi computer. I would be interested to know whether other iPad users have the same experience, or if I'm missing something.
Update: I think the speedtest.net apps for both the iPhone and the iPad are a joke. The speedtest.net app for the iPhone tells me I'm getting 12MB, and that's ludicrous. Does anybody have an opinion whether the dslreports iPhone browser speed test is reliable (
http://i.dslr.net/iphone_speedtest.html). Using that test this morning, I get about 3MB on both my iPhone and iPad. That's a better match with what I'm experience than the speedtest.net numbers.
Could slow browsing be a Safari issue? Could be my imagination, but the new Opera browser on the iPhone seems faster than Safari.
