2ms to generate, 1 second for basic text to appear and 20 more seconds to receive the whole page on my phone in the centre of town, due to poor service.

Compared with waiting on a blank page for ages, sometimes it's nice to see text content if it's useful, and to be able to click navigation links early. It's much better than pages which look like they have finished loading but important buttons and drop-downs are broken without any visible indication because there's JS still loading in the background. I'm also not fond of pages where you can select options and enter data, and then a few seconds after you've entered data, all the fields reset as background loading completes.

All the above are things I've experienced in the last week.
