I've noticed something similar on my Linux machine.  If I run "rsync
-v" at a virtual terminal (not through X) to back up my hard disk to a
locally attached external disk, rsync runs considerably faster when I
select a virtual terminal other than the one to which it is printing
its messages.  I don't know what is going on here but I agree with
Carles that it probably isn't specific to rsync.
