It's a long time since I used a machine as slow as 2.66MHz. Even the
original IBM PC-XT was 4.77MHz :-)

Look at its dependencies. e.g. try "require 'activesupport'" before
"require 'activerecord'" and time those two separately.

You could also try it without rubygems, e.g. instead of require
"rubygems" do
$:.unshift "/usr/lib/ruby/1.8/gems/1.8/activesupport-2.3.2/lib"
$:.unshift "/usr/lib/ruby/1.8/gems/1.8/activerecord-2.3.2/lib"
... etc

This is also a good way to find out what gem dependencies you have.

Regards,

Brian.
