Bug #4525: Exponential performance when summing Enumerable
http://redmine.ruby-lang.org/issues/4525
Author: Ivo Wever
Status: Assigned
Priority: Normal
Assignee: Koichi Sasada
Category:
Target version: 1.9.x
ruby -v: ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
=begin
When you sum an Enumerable (using .inject(:+) or in a more verbose fashion), 1.8.7 and 1.9.2 show exponential performance, where JRuby and Rubinius show the expected linear behavior.
class A
attr_accessor :foo
def initialize(foo)
@foo = foo
end
def +(other)
A.new(self.foo + other.foo)
end
end
(10..15).each do |factor|
start = Time.now
([A.new(2)] * 2**factor * 100).inject(:+)
puts "#{2**factor * 100} took #{(Time.now - start)} s."
end
