[TYPO3-english] Browser Loading Issue with TYPO3 4.2.6

[Nick Weisser]

Hi there,

I'm having a weird "performance" issue in the frontend with TYPO3 4.2.6 
that disappears when logged in to the backend.

The frontend pages render instanteneously, but the page keeps loading 
for up to 10 secs:

Any ideas/comments as to what the reason for this might be would be very 
much appreciated :-)

Regards,
Nick

P.S. I wonder if it's possible to find out what the browser is trying to 
load after the complete page has already been rendered.
