Too small transaction sizes? How many elements do you create per transaction? Each tx.close() -> commit forces a disk flush, and if the ration between data creation and disk flush is too small, then you spent all the time waiting for your disk. You should batch them (or test with 2.2. when the first milestone comes out, this issue is addressed there)
