What speed cpu do you have? It shouldn't be taking that long. It's been quite a while since I looked at the import code, but IIRC, our forums took less than an hour to import (we have a little more users and posts than you). Our server currently isn't all that powerful (a AMD Athlon 900MHz, 1GB memory), so unless you have a much slower system, I don't see why it's going so slow. If I have time later today, I'll try running the import on my own system and seeing if there has been code changes which have affected the import scripts. You are using v1.1.6 right?
