[TYPO3-mvc] Extbase - bad performance when not default language

[Jan Kornblum]

Sorry, the relations are: B < 1:n < A > n:1 > C ;) But for testing, 
i've just removed all relations from tca and the models to find out the 
reason for performance issue:

Now i fetch all A-records (~2.000) using $repo->findAll(), and iterate 
over them using a foreach inside the controller. Nothing is being 
passed to fluid, no other code is called from this plugin.

Calling the page containing the plugin now takes about 3 seconds in 
L=0, but nearly 9 seconds in L=1.

As soon as i remove the iteration (the plugin now simply does 
$repo->findAll() and nothing more), calling the plugins page takes 2 
seconds in L=0 as well as in L=1.

Is this a common behaviour in extbase?? I can't believe that 2.000 
records (all tranlated once) in conjunction with a simple iteration 
over them could lead to such a big performance difference!?

What am i missing?

Kind regards, Jan

P.S. The situation above is just an example to find out the reason for 
this bad performance. The real application needs some more iterations 
and calculations, which leads to unacceptable execution times in L=1.
