[TYPO3-mvc] ExtBase performance

[Tomita Militaru]

Hello,

I am trying to import a CSV file with over 65.000 records using an 
ExtBase extension I'm building. But seems like that ExtBase can't handle 
that many objects or are too many as it takes nearly 30 minutes to store 
them in the database.

To test, I tried something like this:

$persistenceManager = 
t3lib_div::makeInstance('Tx_Extbase_Persistence_Manager');

for($i = 0; $i < 65000; $i++) {
         $objectNew = 
t3lib_div::makeInstance('Tx_MyExtension_Domain_Model_Object');

          $objectNew->setZip('123456');
          $objectNew->setHouse(5);
          $this->objectRepository->add($objectNew);
}
$persistenceManager->persistAll();


Should I just do it with plain INSERTs as it worked much better using 
that method? Is there a more efficient way to store objects in ExtBase 
that I am not aware of?

Thanks!
