[MacRuby-devel] macruby 0.5 is 10x slower running rexml than MRI

I thought this was a very strange result: $ ruby xml_benchmark_rexml.rb user system total real rexml 8.990000 0.540000 9.530000 ( 9.609303) rexml 8.900000 0.540000 9.440000 ( 9.555908) $ macruby xml_benchmark_rexml.rb user system total real rexml 90.910000 3.240000 94.150000 ( 53.791530) rexml 92.760000 3.110000 95.870000 ( 52.334891) xml_benchmark_rexml.rb and associated xml data file are located here: http://svn.concord.org/svn/projects/trunk/common/ruby/xml_benchmarks/
