All rails scripts running slow -- require_frameworks() probl

I'm using InstantRails to build my rails app. Anytime i try to run a rails script (the two i usually run are `ruby script/server webrick` and `ruby script/runner 'Mailer.check_mail'` (an ActionMailer to check a GMail account over IMAP and retrieve messages). I have profiled both of these applications with Ruby Performance Validator, and they are both spending like 98% of the time at require_frameworks(). I can see that as being acceptable for webrick, but why would the mailer script be running so slow, especially after I have webrick (and the associated frameworks) loaded and running?

I have tried messing around with setting RUBYOPT=rubygems, but that doesn't seem to help.

I am on a windows box running Ruby 1.8.6, Rails 2.0.2. Any help would be appreciated!

script/runner loads the entire framework (it's kind of the point of it) so it's never going to be lightening fast. If you're going to be running the script often you may be better off with a long running process rather than thrashing around reloading rails every 30 seconds.
