Summary: Mega slowness in custom require
Initial Comment:
I recently upgraded to rubygems 1.6.5 and started experiencing a major slowdown
loading the environment for a Rails 2.3 application.
I traced the problem back to the Kernel.require (custom_require.rb) and
Gem.loaded_path?. It seems that searching $LOADED_FEATURES repeatedly is
inefficient and results in a 4x slowdown in my specific case.
I've downgraded to rubygems 1.3.5 which doesn't suffer from this problem. This
is a major hurdle to developing in ruby, as it takes me ~45 seconds to load the
environment and run one test.
Below is some console output demonstrating the problem.
/www/aboutus/app_root [master] $ time rake environment
(in /www/aboutus/app_root)
