I’m migrating a many-years-old large forum from Discuz to discourse.  
there is about 100k users, 3M posts and 150GB attachments.

I’m using the discuz\_x import script to do this now, but it’s very slow, and may take many many days to finish it.

is there any advice for me writing a faster import script?
