[TYPO3-mvc] Does the Persistence Layer not respect dirty objects?

[Thomas "Thasmo" Deinhamer]

Thanks for your reply!

What I have figured out is, that if I add hundreds of
objects via $repository->add() and call persistAll()
once at the end, it inserts those hundreds of objects
into the database in a few seconds only.

But if I call persistAll() after every ->add(),
it can only handle a handful of objects per second,
which is really, really slow. It seems to be a
performance loss of a factor of about 10.

Is the only way of having a good performance here,
to add a custom cache which would hold already
instantiated objects or can I speed up Extbase's
persistence/query layer in some way here?

Thanks you,
Thomas
