It depends on your hardware. On a modern multi-core CPU you can get it down to 3-4 hours I believe, and I think the final message is something like “recon-all finished in…”

External Email - Use Caution hi

How long does it take to execute a recon-all command?

and what message indicates that it finished?

Is there a way to speed it up?

thank you
