[TYPO3-mvc] Extbase performance issues

[Alexander Dick]

Hi Folks,

I developed an extbase application where people can apply for different 
jobs via the frontend, the applications are then being processed in the 
backend by different editors.

The data structure of such an application is rather complex, there are 
lots of different models and relations.

The problem is:

In the backend module we have a list of all applications, sort- and 
filterable by different properties (which belong to different related 
models). Also there is a start and end date filter to limit the records.
In the beginning all went well, as there were not much applications yet.

Now we have > 1500 applications and the list takes about 30 to 60 
seconds to load. The cause is obvious - there's a huge amount of objects 
that have to be loaded in order to display that table.

Simplest solution would be a pagination but I wanted to ask you guys if 
I could make something different to improve the performance?
Is there a trick speed up things when it comes to lots of objects in 
extbase?

Thanks a lot
Alex
