Webrick is very slow to respond. How to speed it up?

I have a Rails application that I'm running on my server. When I go to a remote desktop and attempt to load the application, the server takes a good 3-4 minutes to respond with a simple HTML page. However, when I load up the page locally on the server, the page shows up in just a second. I tried pinging the server from my remote desktop and the pings are going through successful in a reasonable amount of time.

This all seems to have started after I installed Oracle's basic client and SQLPLUS. Should I suspect Oracle? Has anyone experienced anything similar to this?

Just had the same problem. The

...
:DoNotReverseLookup => true,
...

did the trick for me too. Just in case you´re running ruby under the rvm, here is the path to go for:

~/.rvm/rubies/ruby-<version>/lib/ruby/<version>/webrick/config.rb

"Thin" is now a great option for running both locally and on Heroku:

On Heroku: https://devcenter.heroku.com/articles/rails3#webserver

Website: http://code.macournoyer.com/thin/

You can use it locally by putting in your Gemfile:

gem "thin"

... and then run bundle and start your server with thin start or rails s.

Update on Heroku

Thin is now considered a bad choice for Heroku. More information here:

Their recommendation:

Switch to a concurrent web backend like Unicorn or Puma on JRuby, which allows the dyno to manage its own request queue and avoid blocking on long requests.
