[TYPO3-mvc] Endless loading time Extbase plugin with FE user logged in

[Lorenz Ulrich]

Hi there

I'm currently developing on an extension that I kickstarted with the 
Extension Builder. When I call a page that contains the plugin, I get 
the list created by the Extension Builder in a reasonable time.

As soon as a frontend user is logged in to the site, the same request 
takes about 30 seconds of rendering time without any error messages.

Did anyone ever experience that as well?

Best regards,

Lorenz
