[TYPO3-mvc] Performance of $persistenceManager->persistAll() (Dispatcher) and findAll() (Repository)

[Dominik Stankowski]

Hi all

Thank you so much for all the work done on extbase and fluid. We are 
currently developing an Intranet application and it is a lot of fun 
working with extbase and fluid.

Now that we see everything play together, we experience some performance 
issues which we have tracked down to the two functions

(1) findAll() in Repository.php and
(2) $persistenceManager->persistAll()

which seems pretty obvious, as these functions do most of the "hard" work.

However, I was wondering if there is a way to improve performance 
slightly, as both methods consume about 5s each to load 300 records 
(with 2 sub-records each - let's call them "type" and "cat"). The whole 
page loads in about 12s.

For findAll(), we have applied lazy loading where possible which has 
slightly improved the output. Is there a way the objects could be cached 
so that they would be available with the next call instead of being 
loaded again?

For the persistence manager, I am wondering if there would be a way to 
enable/disable it, especially for views which are not modifying data.

Thank you for your hints.
