Thanks for your it worked Now to test the performance difference
between Ruby1.9.1 and ruby 1.8.6 with rails 2.3.2 what I did is

Hello,
First, you should delete the file public/index.html if you want another
controller to be called on your home page.
Once it's done, you just have to add the line
map.root :controller => 'your_controller'
(and maybe the action required if it's not index) to your config/routes.rb
and it's
Delete or rename public/index.html ?

Hi In my machine there is Ruby1.8.6 ,1.9.1 and rails 2.3.2 And I created
a new project using Ruby1.9.1 and rails 2.3.2 But when did
./script/about it shows
Ruby version 1.8.6 (i386-linux)
RubyGems version 1.3.1
Why this happens
Thanks in advance

Tony,
If you're looking for super simple deployment, I'd recommend switching
to http://Heroku.com. It doesn't get any simpler and their entry
level service is free. You should have your application deployed in
less than 30 minutes.
