I''m using Apache''s HTTP server, and finally got it configured to the point where my pages will load, but they take an average of 15 to 20 seconds to load. I''ve tried to search all areas of Ruby on Rails and googled my questions but wasn''t able to find a solution. WEBrick flies like the wind, but I plan to move this app onto a hosted website that uses Apache. I''m following along with "Rails in 4 Days", so I''m not using a large database, and everything is local. The Apache version I''m using is 2.0.53 for windows, Ruby 1.8.3, and the latest Rails/gems installation/update. Could someone provide a concise set of instructions for configuring the server, or point me to something with these instructions? I''ve found several articles and the "video" in Rails Academy, but nothing seems to help. I''m certain I have whacked my config so badly that the requests are going to Mars before they come back. Thanks for your help, Brian
Brian- I''m gonna assume (safely, I believe) that you''re running using CGI under Apache. In those conditions, it''s unlikely that any amount of tuning will do much to speed up your rails application. In my experience it, unfortunately, seems that RoR requires so many outside files, that it just doesn''t run very fast in a standard CGI environment, because of all the time it takes to load and parse all those require''d libraries. If you can, try setting up RoR to run with either mod_ruby or FastCGI. Out of curiousity (list-wise), has anybody figured out anyway to tune the CGI to be slightly faster, or is there just nothing to be done?

Speeding up CGI is a uphill battle. CGI is just not a technology which is up to modern web applications requirements. Here is what happens for each cgi request: * Staring ruby binary * Compiling half the ruby standard library + all of rails * Generates all the active record code dynamically from your database schema * Execute your code * Terminates With fastcgi the only thing which is done for each request is the code execution phase.

I tried setting up FastCGI and mod_ruby - what I couldn''t determine is if this is an either one or the other case, or if I can set up both. I couldn''t tell the difference between mod_ruby or FastCGI, primarily because I''m not sure if I''ve got them configured correctly. In any case, I wouldn''t think it would take that long to load a web page. I also can''t imagine CGI lasting this long with page loads as long as this. Does someone have the steps required to setup FastCGI and/or mod_ruby? As I mentioned previously, I''ve found various items on the web site but nothing conclusive, or up to using the current versions of ruby, rails and apache. I forgot to mention that I also tried the Ruby for Apache One-Click installer but that doesn''t seem to help.

Brian- It seems likely that you were probably still using standard CGI when tryting to get FastCGI/mod_ruby working. The most important change you need to make to get either FastCGI or mod_ruby working is updating the .htaccess file in the public directory. By default this file will map all your Rails-requests through dispatch.cgi (with the line RewriteRule ^(.*)$ dispatch.cgi), so to make it work with mod_ruby, you''d change it to dispatch.rb and to make it work with FastCGI you''d change it to dispatch.fcgi. Hopefully that''ll get you closer. Just FYI- If you switch to FastCGI and it''s executing dispatch.fcgi correctly, you ought to see messages to that effect in your error_log for Apache. If you get actual error messages (about not connecting, shutting down, etc), post those to this list and I''m sure somebody can help you figure it out.

Granted they are special engineered, one off machines. Watch tractor pulls some time to see many multi engine machines. There are still some 5 or more engine machines out there. For Rails, you can only use one or the other at any specific time.> > I couldn''t tell the difference between mod_ruby or FastCGI, primarily > > because I''m not sure if I''ve got them configured correctly.

While you might not notice it via seat of the pants timing, it looks like perl could be faster at loading and running. :~$ time ruby -e ''puts("Hello world \n")'' Hello world real 0m0.007s user 0m0.004s sys 0m0.002s :~$ time perl -e ''print("Hello world\n");'' Hello world real 0m0.002s user 0m0.002s sys 0m0.001s> > Does someone have the steps required to setup FastCGI and/or mod_ruby? > > http://www.modruby.net/en/doc/?InstallGuide >-- Steven Critchfield <critch-wQLwMjUOumVBDgjK7y7TUQ@public.gmane.org>
Are you running a production environment or development? It makes a big difference.

Ok, first off, could someone please tell this ignorant fool how to reply
to these messages? :-[
Thanks for all the help so far - but I''m still having a problem getting
FastCGI to work.
Apache''s error.log shows:
"[Sun Mar 27 07:47:47 2005] [notice] Apache/2.0.53 (Win32)
mod_fastcgi/2.4.2 configured -- resuming normal operations
[Sun Mar 27 07:47:47 2005] [notice] Server built: Feb 10 2005 06:11:34
[Sun Mar 27 07:47:47 2005] [notice] Parent: Created child process 2444
[Sun Mar 27 07:47:48 2005] [notice] Child 2444: Child process is running
[Sun Mar 27 07:47:48 2005] [notice] Child 2444: Acquired the start mutex.
[Sun Mar 27 07:47:48 2005] [notice] FastCGI: process manager initialized
[Sun Mar 27 07:47:48 2005] [notice] Child 2444: Starting 250 worker
threads."
I assume from this that FastCGI is up and running.
When I try to go to: "http://todo/categories/list", the following is
displayed:
#!c:/ruby/bin/ruby
require File.dirname(__FILE__) + "/../config/environment"
require ''dispatcher''
require ''fcgi''
log_file_path = "#{RAILS_ROOT}/log/fastcgi.crash.log"
FCGI.each_cgi do |cgi|
begin
Dispatcher.dispatch(cgi)
rescue Object => e
error_message = "[#{Time.now}] Dispatcher failed to catch: #{e}
(#{e.class})\n #{e.backtrace.join("\n ")}\n"
begin
Logger.new(log_file_path).fatal(error_message)
rescue Object => log_error
STDERR << "Couldn''t write to #{log_file_path}
(#{log_error} [#{log_error.class}])\n" << error_message
end
end
end
I think this is telling me it can''t write an error message to an
apparently undefined log file. I haven''t messed with any log file
definitions so I''m not sure where to go with this.
One other thing that puzzles me is the "#!c:/ruby/bin/ruby" line. I
changed this to be "#!c:/ruby/bin/rubyw.exe" in the dispatch.cgi file.
Thanks again for all your help.
