I tried the same thing. Came to the same conclusion. I tried emailing 
Ari, but haven't got any response. I am also not sure if I use it 
correctly. I would like to know a way how I can query if I am actually 
using the c fastcgi version.

Here is what I wanted to send to the list a couple of weeks ago, but 
never did. Something else came up and I am not sure I even finished the 
mail. Nevertheless here it is:

Hi folks,

I have tried to contact Ari (the maintainer of webrick-fcgi) with this,
but he still hasn't answered in a couple of days. Maybe he is not able
to at the moment. My questions are better asked on the list anyway.

I am trying to get webrick-fcgi to work on the Cygwin platform. What I
am not really sure about, is how to find out if it really works the way
it should and how to configure it properly.

### fcgi.rb
require 'fcgi'
require 'webrick/fcgi'

include WEBrick

dir = File::dirname(File::expand_path(__FILE__)) + '/test'

puts dir

s = WEBrick::HTTPServer.new(
   :BindAddress    => "0.0.0.0",
   :Port           => 8088,
   :DocumentRoot   => dir,
   :Logger         => WEBrick::Log::new($stderr, WEBrick::Log::DEBUG),
   :CGIPathEnv     => ENV['PATH']  # Especially for Cygwin
)


## mount subdirectories
trap("INT"){ s.shutdown }
s.start
###

my test script for cgi/fcgi (from rubygarden)


### test.cgi and test.fcgi
#!/usr/bin/env ruby
require 'cgi'
require 'fcgi'


FCGI.each_cgi do |cgi|
   content = ''
   env = []
   cgi.env_table.each do |k,v|
     env << [k,v]
   end
   env.sort!
   env.each do |k,v|
     content << %Q(#{k} => #{v}<br>\n)
   end
   cgi.out{content}
end
###

when I access this script with http://localhost:8088/test.cgi I get the
output, but when I access http://localhost:8088/test.fcgi I am asked if
I want to download the file. How can I get the fcgi file to execute
properly or better yet make custom mappings (*.rb files get executed by
fcgi).


Benchmarking gives me:
$ /usr/sbin/ab http://localhost:8088/test.cgi | grep Request
Requests per second:    3.21 [#/sec] (mean)

this probably means that fcgi is never invoked cause my computer AMD
2600+ should be a little faster.
------------------

Maybe someone can explain how this module is used correctly?

Thanks
