How fast does your Ruby run?

I got 53648 iterations per second running the following program,
on an Intel 3.2 GHz HT, Win XP machine:

--------

C:\> ruby calculate.rb
55

Ruby 1.8.6 patch 0 on i386-mswin32
It took 18.64 seconds to run. 53648 iterations per second.

--------

n = 1_000_000

start_time = Time.now

for i in 1..n
t = (1..10).inject {|x, y| x + y }
end

finish_time = Time.now

p t

puts
print "Ruby ", RUBY_VERSION, " patch ", RUBY_PATCHLEVEL, " on ",
RUBY_PLATFORM

puts
print "It took #{finish_time - start_time} seconds to run."
print " #{(n / (finish_time - start_time)).to_i} iterations per
second.\n"

It took 5.920011 seconds to run. 168918 iterations per second.

I changed the scope of x & y and eeked out some more speed.

x, y = nil
for i in 1..n
t = (1..10).inject {|x, y| x + y }
end

As you are seeing, ruby 1.8.x is painfully slow on Windows. =(

That cut almost three full seconds off my time -- down to 13.829852
seconds to run, at 72307 iterations per second. Obviously, you're still
kicking the crap out of my poor little Pentium M.
