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

[Jan Kornblum]

Dear newsgroup,

i've got a very performance intensive extbase extension. I did some 
code modifications on it to get it faster. Now the extension works 
faster, but only as long as the default language is selected. As soon 
as another language (currently there is only L=0 and L=1) is selected, 
there is still a very bad performance.

The extension contains three related models: B < n:1 < A > 1:n > C

In short, the code iterates through the estimated 2.000 A-records and 
does some calculations depending on their related B- and C-records.

I wonder why this is so slow for any other language then the default 
language. Are there any possibilities to influence this behaviour?

Kind regards, Jan
