Mongrel is multithreaded

Feel free.

Run apachebench against this ruby script.

The test is for performance on one core, so if you have more use
schedtool to set the CPU affinity (and run apachebench on another core).

schedtool -a 0 -e ruby mongrels.rb
schedtool -a 1 -e ab -n 10000 -c100 http://127.0.0.1:3000/?name=TLUG


require 'mongrel'
require 'cgi'

class SimpleHandler < Mongrel::HttpHandler
  def process(request, response)
    response.start(200) do |head,out|
      head["Content-Type"] = "text/html"
      name = CGI::escapeHTML
        (CGI::parse(request.params['QUERY_STRING'])
         ['name'].to_s)
      out.write("<h1>Hello #{name}</h1>")
    end
  end
end

h = Mongrel::HttpServer.new("0.0.0.0", "3000")
h.register("/", SimpleHandler.new)
h.run.join
