The progress bar reaches 86% within 2 minutes but the from 'generating object: 2600 items progressed' and above the progress of items progressed is very slow, e.g. 2608 after 10 minutes. I have tried this 3 times and it has crashed each time. For my last attempt it crashed at 2608 after about 11 minutes.
