Hi Zoltan,

I'm using a mongrel_cluster behind an apache load balancer which works
fine with SSL. Then you can do alot of performance stuff in Apache
beforehand.
If you want more performance think about using erubis instead of
plain/old erb and imho you're not forced to use the big ActiveRecord
when you're using Rails. Personally I like Sequel but you can do your db
stuff with OG too.
You can also define different database connections for your models which
disburdens your DB server.

... ahhh, there are quite some performance tips for Rails out there. Or
you use Camping or Merb which are significantly smaller, and so on...

Cheers
Florian
