Ruby 2.0 slowness with big concurrency

To reproduce:

  1. Install redis locally and checkout the Sidekiq repo:
git clone git://github.com/mperham/sidekiq
cd sidekiq/myapp
bundle
  1. Load lots of jobs into Redis:
> time bundle exec rake load_jobs
2013-04-26T15:32:37Z 66670 TID-ov6pgqt3k INFO: Sidekiq client using redis://localhost:6379/0 with options {:size=>2, :namespace=>"foo"}

real	0m49.206s
user	0m45.037s
sys	0m3.558s
  1. Start Sidekiq with 200 worker threads to process those jobs. You will need to kill Sidekiq with Ctrl-C as soon as log messages stop flying by.
> time bundle exec sidekiq -c 200

  1. Now try with various Rubies to see how your choice in VM performs.
