This. I have my own site slim and lean even with javascript (analytics) in there and it loads in 300-500ms. I developed a site for a client that was slim and lean and then it started. Sliders, full page background images, photos of random people, 3x analytics, this and that. It became a mammoth of 2-3mb and loading times of 1.5-3s.<p>When we tracked conversion the best converting page on the site was one made specifically for that and it is 100kb and loaded instantly. Two images and lots of text. They still insist on slow, beautiful pages elsewhere instead of making them convert as well.
