Hi all,
i need to import a csv-file with about 58.000 Lines und 60 Columns. I have 8 Entitys where the values will be stored. 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
