Aurélien,

Deleting is faster for me : it took 2 seconds to delete 9 objects, with a save between each deletion. With a save only when all objects are marked for deletion, it took around 0.2-0.3 second.

This is faster but it is still slow to me. Mainly because I'm on a good computer and I'm afraid of the results on small G4...


Eric.

i have the same problem too, and not only while saving, but while deleting too !
can you test deletion of several managed objects then save ?

Hi !

Is there a way to improve the saving performance of a SQLite persistent store ? On my respectable PowerMac 2x2,3Ghz, it takes around one half of a second to save...one managed object !
I'm developing an accounting application and each new transaction is saved to the persistent store when the user submit it. Well, let me tell you that one half of a second if way too slow to be acceptable - and I'm not even talking about the performances on older computers than mine !


Maybe I should save the changes only when the user quit the application (just like it is done by default) but if an user work on the app for 2 hours and then a power failure happens, everything would be lost !

Can anyone give me advice me on this ?


Thanks,

Eric.
