Running Ruby on Rails on Sun Java System Web Server 7.0

I don't know a ton about that system, and I don't have time to read
the details, but they're discussing, I believe, it's performance on Java

The RoR page discusses installing with FCGI, which is a no-go-zone
from my
perspective. Why voluntarily submit yourself to torture when mongrel is
available thanks to Zed's hard work?

One thing I will absolutely lay-down-in-front-of-a-train if I'm wrong
is this: Using that web server will not make your Rails applications
as fast as hosting them under Apache+Mongrel or Nginx+Mongrel.
