Tom-
If a point of reference if any help in your decision, we've been using
a setup similar to topo #3 except with two web/app servers. Currently we
serve about 2 million hits day (most of these are images served into our
emails) off the cluster. Vmstat, even at peak times, never shows more
than 12% CPU load, and swapping is non-existant (thank you apache!). Our
application isn't extremely db intensive, nor is it session based, so
YMMV, but for sheer volume, a smaller setup will suffice.
