Rails development processes running very slow

This is a problem I know other people have been having. I'm on Rails
2.3.5 on a dual core 2.1Ghz Macbook Pro 2.1 with 3Gb of ram and 800Mb+
inactive memory. Things should be fast. Sometimes things run slowly,
but nothing nearly as slowly as rails. irb starts in milliseconds.
Even Java maven tasks are pretty fast. Rails on the other hand takes
a pitiful 1:30 minutes to start - the server, console, and tests.
Simple requests often take 5-10 seconds.

My ruby version:

ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin9.7.0]

I do have 208 gems installed, many of which are in use. That could be
the issue, or it could be some specific gem that's causing a problem.

Either way, I'm presently missing the startup speed of Java, which
seems rather ironic.

My last rails project was with earlier versions when I never had a
problem.

Are there any known problems with gems or anything else that cause
this kind of issue?

Thanks.

I hope someone figures something out with this - I'm having similar
issues with ruby 1.9.1 and rails 3 on Windows, Ubuntu 9.04 or 9.10.
Nothing I do seems to help with the load time at all (30-60 seconds).

Alright.. Are you starting in development mode or in production mode?
Can we see your environment.rb (or the part that relates to gems anyway)
?
How big is your database?
Are you setting up activemailing ?

I'm running in development. Rails 3.0.0.beta, ruby 1.9.1p378.
My database is small (10 tables, 5-10 columns a table).
No activemailing.

My environment.rb (pretty sparse):
# Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
TestHarness::Application.initialize!

My Gemfile:
source 'http://gemcutter.org'
source 'http://gems.github.com'
gem "gemcutter", "0.4.1"

# Rails3 beta
gem "rails", "3.0.0.beta"

# ActiveRecord requires a database adapter.
gem "ruby-mysql"

# Gems required for the AftershockHarness
gem "watir", "1.6.5"
gem "firewatir", "1.6.5"

# shoulda and factory_girl both have bugs in relation to Rails 3. So,
for now use the the repositories
# in vendor/git.
# These gems are both built from the git repos in vendor/git and then
copied over to vendor/cache.
# If for any reason you need to regenerate these gems, cd into vendor/
git/<library> and then
# issue a 'gem build <library>.gemspec' command. This will produce a
new .gem file, which can be copied
# (or moved) into vendor/cache.

# Gems only used for testing
group :test do
  gem "webrat"
  gem "cucumber"
  gem "shoulda"
  gem "factory_girl"
end

# Gems only used for development
group :development do
# gem "ruby-debug19", "0.11.6"
  gem "wirble"
end

Okay.. Did you do 'bundler lock' ?
(I am shooting blind here, I'm confused by the problem, but sometimes
it's like playing broadsides.. start shooting and it starts making
sense!).

Either way it's slow. with the bundle locked or not.
