As long as I have something to read while the rest of the images and videos are loading. I don't mind slow page loads. But, I dislike those pages which are blank and takes a long time to load text.
as long as the page don't take so long that I could get up and get a glass of water or something I'm fine with a low slowness. Unless I'm in a hurry or pay for fast sites.
to me it's pretty important.. i'm so fast paced web surfer anyway. nothing is worse when you're in hurry and some important site takes like 1 minutes to load. grrr
