I have noticed that when my internet connection is a bit slower all my wp sites take up to five minutes to load Google Chrome when I am logged in. The version of google chrome I am using is 17.0.963.83.
When I logout the site loads fine again. The dashboard also loads fine when I am logged in and I know it's not a problem with my theme because the same thing happens applies when I apply the default twenty eleven theme.
I have set up a dummy subscriber user so you can test it yourself (to see the difference between the logged in states you need a slow connection though :p)
Does anybody have an idea why this is happening?
