Mean Mail Machine

i was trying the other day to create some sort of a newsletter. sadly it took me about 2 hours to generate and send 51000 emails (not spam :) ) so i tried to find a way to do it a little faster.
a friend of mine came across the idea of using threads so i tried to override the basics of ActionMailer in order to make the delivery method to user threads.
the change boosted me up to 18-20 mails per second, in other words, 1900% more efficient!
here is the code, just push it in your environment.rb (or lib, whatever), just don't use it for mean/nasty/microsoft needs :).

  1. ActionMailer::Base.delivery_method = :thread_smtp  
  2.   module ActionMailer  
  3.     class Base  
  4.       def perform_delivery_thread_smtp(mail)  
  5.         thread = Thread.new do  
  6.           perform_delivery_smtp(mail)  
  7.         end  
  8.         thread.run   
  9.       end  
  10.   end  
  11. end

Nice. But you don't need Thread.run. Be careful that your program doesn't exit before the thread completes or it won't get to finish its work.
