However, [Safari] still has the best perceived performance. Just open a page with a heavy layout and scroll up and down, or type an address or search term in the location bar and "feel" how fast it loads. The performance gap is particularly noticeable on older Macs. Safari feels about the same as other browsers on my recent Mac... but there's a big gap in responsiveness between Safari and the other browsers on my wif…
Its in Apple's interest to not have Safari work well on older machines (since they want people to buy new machines), or improve it in ways that would make the browser better compete against the app store (especially on mobile). It is in their interest to have it be a very nice looking document viewing platform, which is where I imagine most of their developer resources are going towards.

Then they're failing miserably, because as I (and others in this conversation) have attested to... Safari is noticeably faster than Firefox or Chrome on older Mac hardware.So I don't think your theory holds any water. Sorry.
(Edit: My post was unclear. I and others feel that Safari, despite its other shortcomings, is the most responsive browser on OSX - not the least.)
