Google’s Page Speed vs. 3PMobile
For today’s test I thought I’d use Google’s new Page Speed service (which supports Mobile) and compare the results to our own 3PMobile Performance Measurement service. To make the test “even” I had Page Speed run a test on http://m.cnn.com (CNN’s mobile site) I then ran the same test on our service using my AT&T phone. Here’s how it baked out.
Page Speed score 57 out of 100 (where’s the detail?)
3PMobile metrics. Items to note:
- Cell strength icon, real time GPS and disk cache empty
- Time for the actual test – it’s slow on AT&T
- Device and carrier information
Now lets take a look at how the browser actually performed. Now it gets much more interesting. You can actually see the elements of the page that are causing the big slow down.
- The home page and the style sheet account for a huge chunk of time (there’s actually a redirect taking place which is strange because the URL was already set to go to the mobile site
- There’s a red button which spins the clock
- And finally what looks like a cookie that takes forever to download (it shouldn’t)
- Overall these 4 elements account for virtually the entire delay of 30 seconds to load the page
