I'll grant you that it's a 5.1G tar file, but 7 hours seems excessive.
Depends, both on the machine and the database.
What sort of disk i/o are you seeing, what's the cpu(s) doing, and
what's the restore taking so long over (since you have -v)?
Oh, and have you tweaked the configuration settings for the restore?
Lots of work_mem, turn fsync off, that sort of thing.
