On this dual PII 350 box `make -j 11 buildworld', playing an mp3 with 
xmms and unarchiving two separate mozilla distros can cause quite an 
interactivity problem.  At a more moderate system load things are quite 
usable.  It's still not BeOS, but BeOS never had the kind of i/o that 
FreeBSD has, so I think things are going fairly well.
