So after quickly posting my video blog about answering some of the questions, I was contacted by morfik to help answer some of their iPhone questions. It turns out their doing development for the iPhone and are located across the world in Australia, but have NO IPHONE! So I emailed them and skyped a bit and we started to do some benchmarks for the iPhone.
Its kinda funny because it did not even cross my mind that people would be checking out my youtube videos and not be able to pickup a iPhone at an apple or at&t store. I guess I need to think more globally and feel bad for all those people who CANT get an iPHONE. Anyway, I continued with more testing and wanted to post up my results for the world viewing. Please also feel free to contact me with other test you are interested in or comments, I can always throw up another video blog post to show you more aspects of the iPhone.
Anyway, I did some javascript benchmarks for my 8GB iPhone as well as with my ultra fast Macbook Pro 2.4 GHz Intel Core 2 Duo with 4 GB Ram! (Safari 3.0.2) If you are looking for some javascript benchmarks for the iPhone here they are below:
I ran each of the following test from http://www.geocities.com/SiliconValley/7116/jv_bench.html on my iPhone and Macbook Pro and here are the results.
iPhone
Primes: 0.352 seconds
pgap: 8.702 seconds

The next tests for my iPhone and Macbook Pro took place at http://celtickane.com/projects/jsspeed.php

*sidenote* At this point I did some development and/or Testing on iPhone … So I did some quick testing with some ruby on rails development. I opened a project I am working on and had it running localhost:3000 on my macbook pro. I jumped on the wifi network with my iPhone, open the ip of my macbook pro and bam, saw the project. So YES you can do web development on your machine and easily refresh your iPhone to view your work from any device, pretty simple all web based. (Start your development now!)
And the testing continues, I checked out http://www.quirksmode.org/dom/innerhtml.html Here are the benchmarks for javascript for the iPhone and my Macbook pro:

The Last and Final Test at http://wildbit.com/examples/adding_elements.html
Note: some of these test were taking a bit long on my macbook pro! (imagine that) So I just ran ONLY the the following below:
iPhone
Method Time
document.createElement() 1481
element.innerHTML Optimized 446
element.innerHTML join 1050
element.innerHTML Optimized Large 1444
element.innerHTML join Large 1852
Macbook Pro
Method Time
document.createElement() 24
element.innerHTML Optimized 5
element.innerHTML join 8
element.innerHTML Optimized Large 21
element.innerHTML join Large 27
As I said earlier if you are looking for some other test for the iPhone or have some questions please feel free to contact me and I will try to help. Also if you have more information about the Safari browser running on the iPhone please contact me. I also want to give a shout out to iPhone Dev Camp, I am not sure if I will be going, but I am hoping to at least remote in if possible, if you are in the NYC/VT/New England Area and planning to do some iPhone development, please contact me.
Thanks!
