There are other topologies that scale better, but for most sites it
should work fine. I believe it was one of the people that know this much
better (Horms?) that said that separate directors would give better
throughput. He'd have to explain the specifics of that, but I'm sure
he's correct. I find the 'streamlined' config works best for people that
don't want to spring for the extra machines for directors. I used
separate directors in my last project as the client's machines were
windows boxes, plus I can now use these directors as directors for other
clients clusters with almost no setup required.

The best advice I can give is to test the configuration under load and
see if it meets your needs. 

Horms would be much better at giving the reasons why one config would be
better than the other. He wrote the page, after all.
