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:
