I always got the almost same results on my laptop: (Pentium M 1.5G, 1G ram). I closed all other programs, Excel, Eclipse, browsers, ...before I ran it.
C:\temp>ruby test.rb

I think this shows the speed of my computer more than anything else:

C:\dev>ruby primes.rb
5133
time taken: 2.06 seconds
5133
time taken: 41.82 seconds
Florian again
5133
time taken: 41.86 seconds

Appending this:


puts 'Florian again'

# Florian's version
b = Time.now.to_f
puts Prime.new.inject(0) { |s, x| if x > 50000 then break s else s + 1 end }
printf "time taken: %.2f seconds\n", Time.now.to_f-b
