Subject: Re: Is Ruby suitable to develop a large dynamic web site with a heavy  database usage?

The short answer to the question in the subject is:  Absolutely.

The overall execution speed is less likely to be a bottleneck on a site 
with heavy db usage because the db, in that scenario, often becomes the 
bottleneck.

However, to address the basic issue of running speed, I have sites running 
on Ruby 1.8.x that are completely dynamically rendered, with all content 
coming out of the database, and everything, including the navigation, 
constucted dynamically based on the db content.

These sites are running on a 100% ruby based stack (no Apache, lighttpd, 
nginx, etc... involved), and can do on the order of 1100 dynamically 
created page views per second through a single backend process.  A cluster 
of three backend processes does around 2700-2800 r/s.  I get those speeds 
because I don't go back into the database itself on every request, so they 
serve to illustrate what kind of performance a person can get when the 
bottleneck is NOT the database.  Ruby speed shouldn't be a problem when 
addressing the scalability of a large dynamic web site.
