Don’t know if something like this exists already, but thought I’d  
advertise my script 🙂

Introduction

Rails is slow. Rails in development mode on old computers is WAY slow.  
There is hope, however. Just run it in production mode [fast!] and have  
it restart whenever a file change occurs. Slow to restart, perhaps, but  
far faster than reloading all files per request, which is development  
mode. This allowed me to develop in rails on my 1 GHz PPC [like 6 years  
old] and still consider it survivable.

How to get/run:

code:  
[http://code.google.com/p/ruby-roger-useful-functions/source/checkout](http://code.google.com/p/ruby-roger-useful-functions/source/checkout)  
buried in here is rails/rails\_useful.rb, which contains a function

def fire\_up\_file\_modification\_checker\_thread reload\_dirs =  
[‘app/controllers’, ‘app/schools’, ‘app/models’], death\_dirs =  
[‘app/helpers’, ‘config’,  
‘app/controllers/shared\_search\_code\_module.rb’]

so put that file in your lib dir, include it in your environment.rb,  
and, if it’s like mine, add something like this to environment.rb

require ‘lib/rails\_useful.rb’  
require ‘socket’  
fire\_up\_file\_modification\_checker\_thread() if Socket.gethostname =~  
/Roger/ # if you’re on a dev machine  
and watch the goodness go. And then stop. And restart.

Have you seen  
[http://svn.techno-weenie.net/projects/plugins/dev\_mode\_performance\_fixes/README](http://svn.techno-weenie.net/projects/plugins/dev_mode_performance_fixes/README)  
?  
Not used it myself, but it seems to try and address the same sort of  
problem that you are.
