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

I had a vaguely similar problem that manifested itself when accessing a WEBrick server via a VPN. Requests would take a long time, most of it with nothing happening on the wire. Since neither mongrel nor thin gems worked with Ruby1.9 on Windows and there was no way I was getting myself embroiled in compiling stuff from source, I needed to stick with WEBrick.

The fix was to set the config parameter DoNotReverseLookup to true, when creating the WEBrick server:

server = HTTPServer.new {:DoNotReverseLookup => true, ...}
