Safari 4.0.4 on my Macbook Pro is incredibly slow. I type an address in the Safari bar, open Firefox, navigate to the same address, have it load, quit Firefox, and have Safari not even loading a little bit of the page yet. Most of the time it loads background colors (like the light gray at the top of this forum) but then slows to a crawl when trying to load the content. I've tried reseting Safari, not having topsites as homepage, opening DNS, disabling IPv6, deleting a file in the pubsub folder and disabling the fraudulent site warning. All of these things were on the Apple's official discussion forums. While these seemed to have helped a little, Safari 4 is still ridiculously slow compared to Firefox.
