Mongrel users - Sep 2006 - How many mongrel servers should I run in my cluster?

The company I work for is launching a new web site tomorrow.
News of our launch will be published in major publications throughout the
week so I want to make sure we are prepared for the load.

Production Environment:
HP Proliant server w/ 8GB RAM and dual AMD64 Opterons
Memcache is used as the session and fragment store (512MB for it)
MySQL is running on a seperate server in the same rack
We use the mysql gem for Ruby for greater speed and reliability
This server is dedicated to running just this rails app, so how many mongrel
servers should I put in the cluster?
And how many clusters should I setup?

The server needs to survive tens of thousands of page views per hour.

Freshly minted docs on that very subject:

http://mongrel.rubyforge.org/docs/how_many_mongrels.html

And you get a FAQ question too.

Let me know how that works for you.

BTW, waiting until the day before your deployment to set things up is a
really bad idea.  You usually want to be doing this quite frequently and
practicing doing it from scratch for at least a week before your real
deployment.

Haha, yea tell me about it.
Unfortunately this is how things have worked out.

BTW: The cluster is load balanced using the mod proxy balancer in Apache
2.2.2

So you''ll be limited by what Apache will put through.

Just remember too that if you''re not CPU or memory bound yet, or  
doing as much database as possible, you can always put in more  
apache''s and do poor man''s load balancing across those with
DNS.
