A better solution to the problem of sending xmpp in ruby

xmpp4r_faster.rb

require 'rubygems'
require 'xmpp4r'
require 'sinatra'

# Doing XMPP connectivity like this has terrible performance:
# 
# https://gist.github.com/1197232
#
# Here's a better way.
#
# Set up two XMPP accounts:
# "account1@yourserver.org" and "account2@yourserver.org"
# Both with password "password".  
#
# You can change the config to suit your setup here:

JABBER_SERVER = "yourserver.org"
ACCOUNT1 = "account1"
ACCOUNT2 = "account2"


# Start the sinatra webserver server using:
#
# ruby -rubygems xmpp4r_faster.rb
#
# Then let's hit the app with some concurrent connections. Try this at the command line:
# ab -c 25 -n 1000 http://localhost:4567/hi

jid = Jabber::JID::new("#{ACCOUNT1}@#{JABBER_SERVER}/Testing")
@@cl = Jabber::Client::new(jid)
@@cl.connect
@@cl.auth('password')

get '/hi' do
  m = Jabber::Message::new("#{ACCOUNT2}@#{JABBER_SERVER}", "foo").set_type(:normal).set_id('1').set_subject("blah")
  @@cl.send m 
end


# Results are a lot more satisfactory this time, compared to the previous gist:

# ab -c 25 -n 1000 http://localhost:4567/hi
