Are you creating the objects and saving them all at once? If so, that is your problem. Save them in batches of 500 or 1000 and it will go much quicker. You might want to try making a new editing context for each batch.

The conversion of a line to entitys takes almost no time. But the full prozess, from conversion until saveChanges is done, takes several hours (5-6h). After profiling it points me to the generating of primary keys. This part uses half of the time. I need to do the import several times. Do you see a way to improve the speed? I'm using WebObject 5.4.3 (with Wonder). My Development is on Mac. Database is a Frontbase in the cloud on centOS. Thanks for any advice. Tobias
