The <i>initial</i> page load matters a lot.  That&#x27;s the one where the user is deciding whether he&#x27;ll be coming back to your site.  The unfortunate thing about many caching technologies is that they speed up subsequent page loads, but do nothing for the initial one.  You still need to pay attention to clean-cache load times.  Indeed, it can often be worth it to pay a cost on total page load time to get first-paint time down - that&#x27;s the time at which the first visual representation of the webpage appears, even if it&#x27;s just the header, layout, and a bunch of boxes.
