Webrick Very Slow When Accessing Applications From Remote Desktop

Question

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?

Thanks.

Answer 1

Use mongrel! Webrick is notoriously slow.

Answer 2

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, ...}

Answer 3

Having the same issue here (even an year later). Under linux you have to do the following:

Look for the file /usr/lib/ruby/1.9.1/webrick/config.rb and edit it.

Replace the line

:DoNotReverseLookup => nil,

with

:DoNotReverseLookup => true,

Restart webrick and it'll work like a charm :)
