The test of time & page speed
As the spider weaves its web around your site, how long will it take to get from the start to the finish? With the mobile web increasingly expanding every webmaster has to look at load times, yes yes I know what your going to say, not that old loading time thing like back in the early 90's.
The web via IPhones
But hey listen, with more and more people accessing the web via IPhones and other touch screen technology getting your pages to load faster increases usabilty and helps google get around your site so it can be indexed.
All this must have an impact on ranking, but I think its so minimal I wouldnt go to crazy about it. You can check you page speed here http://www.webpagetest.org/test
