Safari not loading pages, other browsers doing fine

Hi,

I have an issue many seem to have: Safari 7.0.5 (and now 7.0.6) hangs when loading web pages whereas other browsers (Chrome, Firefox) work just fine. I've ran my tests on WiFi with two different routers as well as through iPhone tethering.

Here are the steps I have taken so far but the problem persists:

- re-installed my MacBook Air completely with the latest image from the App Store

- Reset Safari

- Disabled extensions

- Unchecked "Warn when visiting fraudulent website"

- Unchecked "Stop plug-ins to save power"

- In the Develop menu, checked "Disable caches"

- In WiFi settings, disabled IPv6

- Changed DNS to OpenDNS

- Deleted all Safari plist, caches, favicons cache, etc.

- Turned off Safari in iCloud settings

- Fixed permissions, rebooted

- Disabled the prefetch setting from terminal

- Emptied all my logs, launched Safari and tried to open this url: https://pragprog.com/login . Here is the (anonymised) result:

Any help with this issue is greatly appreciated, it's driving me nuts and currently have to use Chrome.
