find -exec surprisingly slow

Hello,
I'm in the process of cleaning a Maildir full of spam. It has
somewhere in the vicinity of 400K files in it. I started running
this yesterday:
find . -atime +1 -exec mv {} /home/paulh/tmp/spam/sne/ \;
It's been running for well over 12 hours. It certainly is
working---the spams are slowly moving to their new home---but it is
taking a long time. It's a very modest system, running 4.8-R on a
P2-350. I assume this is all overhead for spawning a shell and
running mv 400K times. Is there a better way to move all files based
on some characteristic of their date stamp? Maybe separating the find
and the move, piping it through xargs? It's mostly done now, but I
will know better for next time.
