I have over a million files I rsync to about a dozen locations every
day. I'm pretty sure I have more dirs, but not tons more. Most of the
locations are remote offices, but when I rsync over a local 100Mbit
segment it still takes about 2 hours just to verify the files/dirs on
both sides in a no-data-change situation.

In other words -- I'm interested in these different optimizations as

My client/servers are a solaris linux mix. I don't have the 2G of RAM on
all boxes to support a single rsync so it gets broken down into a
for-loop across some top level dirs.
