Comment(by jordan.breeding@…):

 Since there was a big change in MacRuby last night I thought I would
 upload fresh timings, and this time I also made sure that nothing else was
 going on on the machine at all during the timings.

 small run:
 {{{
 (; ruby1.9 ./small_queue_test.pqueue > /dev/null; )  11.76s user 0.05s
 system 99% cpu 11.830 total
 (; ruby1.9 ./small_queue_test.ruby_priority_queue > /dev/null; )  20.45s
 user 0.10s system 99% cpu 20.567 total
 (; macruby ./small_queue_test.pqueue > /dev/null; )  16.14s user 1.37s
 system 107% cpu 16.240 total
 (; macruby ./small_queue_test.ruby_priority_queue > /dev/null; )  39.24s
 user 2.13s system 107% cpu 38.481 total
 }}}

 large run:
 {{{

 system 99% cpu 2:02.09 total

 }}}

 This is on a Core 2 Duo 2.0 with 4 GB of RAM installed (but it only uses
 3).
