rsync - Nov 2004 - Copying from one networked filesystem to another

What sorts of options might I give to rsync, to optimize transferring
data from one networked filesystem to another?

Transferring directly between the fileservers is not an option in this
case, for technical reasons.

What sorts of options (or system modifications) might I use to help
rsync get through a HUGE list of files?

We need to be able to add as well as remove files.

We've been using:

/usr/local/bin/rsync \
                        -a \
                        --whole-file \
                        --stats \
                        --progress \
                        --block-size $(expr 1024 \* 1024) . "$dst"

Thanks!

I probably should add some hardware specs:

The networked filesystem clients are 4 CPU, 2790MHz Xeons.

The network between all 3 links (two networked filesystems, one rsync)
is gigabit ethernet, with jumbo frames enabled.

The source filesystem is considerably slower than the destination
filesystem, but I have not quantified to what extent.

Thanks again!
