I went back and ran the experiment again: http://hellohellonico.wordpress.com/2007/07/20/faster-ruby2 I wonder what makes those two tests behaving differently from a jruby point of view. Charles,

In the first case, if Niko is a constant in the current module/class namespace, it will do a single lookup to find it, followed by a single lookup in the Niko namespace to find MY_CONST. In the second example, it will first search the current module or class for MY_CONST and then search the included module for MY_CONST. Both cases work out to two constant hash lookups, so it's strange that one would be faster in Ruby than the other... The second example is somewhat surprising to me.
