rails 2 slow to start after rubygems upgrade

ruby 1.8.7, rails 2.3.8, rubygems 1.6.0

i think this started happening after upgrading to rubygems 1.6.0 (i can't say for sure, i haven't touched this project in over two months). script/server and script/console are both extremely slow to start; around 15-18s, wh开发者_JAVA技巧ich is significantly slower than it used to be. mongrel and webrick are about the same. i know it's not my gems as i put some debug lines in environment.rb after the config.gem lines and they appear to load almost immediately.

oddly enough, rails 3 applications start up just fine. i don't even know where to start looking for the problem.

I'm seeing the same issue with 1.8.7 (p248), Rails 2.3.10, and RubyGems 1.6.1. The slowness immediately showed up for this application directly after the RubyGems update. And, this is a project which is worked on multiple times per week. Skimming the RubyGems Tracker, I don't see any other mentions of this issue.

I'm still seeing the same issue with 1.8.7, rails 2.3.11, rubygems 1.7.2.

I downgraded back to rubygems 1.3.7 to temporarily fix the problem.
