And your other bench. Again, pretty meaningless.

MacRuby does especially poorly here.

system ~/projects/jruby $ cat other_bench.rb
s = "This is a test string"

re = Regexp.new( / test / )

5.times {
puts Benchmark.measure {
for a in 0..1E7
       re.match( s )
end
}
}

system ~/projects/jruby $ jruby -rbenchmark other_bench.rb
