If Linux is running qmail it would have a lot to do with it, but assuming
sendmail on both, was Linux running a name server and FreeBSD not?  Sendmail
really slows down when its not running on a name server.  We had to run
DNS on our mailing list box in a "Cache" mode.  It made a world of difference
to sendmail.  

You gotta make sure your running with the same configuration.  Caching,
swap, memory, async mounts, and other thing will have an effect.  To compare
OS's, you need to be on the same hardware, same setup, and make sure the 
tests are compatiable.
