ActiveSupport::TimeWithZone in Range performance bug
Reported by Bogdan Gusiev | May 13th, 2011 @ 08:28 AM
We discovered that some operations on the Range class of ActiveSupport::TimeWithZone is slow.
Example:
(10.days.ago..3.days.ago).min
Will have more than 5 seconds execution time with both Rails
2.3.11 and 3.0.7 on Ruby 1.8.7.
The problem don't appear on Ruby 1.9.2.
Also the following code doesn't have performance issue:
(10.days.ago.to_datetime..3.days.ago.to_datetime).min
Thanks,
Bogdan

I can confirm it happens on Ruby 1.8.7 and Rails 3.0.0, the example line takes 10+ seconds to run. The "doesn't have an issue" code works instantly as it did for you as well.
