I wrote a custom adapter for importing 6K categories using the advanced profiles. The import is too slow. I've tried increasing the number of records from 1 to 5 but it doesn't help. I also tried using ->setDisplayMode($dispMode) and ->setIsMassupdate(true) before saving the category but it also doesn't help.
Any idea how to speed things up?
Magento importing mechanism is painfully slow. You would be better off inserting the data directly into the database.
