[TYPO3-mvc] Wondering about performance

[Daniel Dimitrov]

Hey Felix,
Thanks for the fast reply!
I thought that lazy loading was the key here and I tried it.
I was confused with the result. Let us say that my description field has the 
@lazy tag in the comment.

In my controller I did this:
$products = $this->listRepository->findAllWithLimit($pages,10);
var_dump($products);

As you see I wrote my own query to fetch the results with limit.
In my var_dump output I was seeing the description variable and it was 
initialized - it had the values from the database.
I thought that lazy loading will set the description variable to 0 and first 
when I try to use it in my fluid template it will be loaded.
Did I understand the principal behind lazy loading wrong?

Regards,
Daniel
