I am sorry, yes.

My 0.02EUR: interpretation of programming languages in other programming 
languages usually does not help improve performance.  I believe the 
approach to let Ruby run on a highly optimized runtime environment (like 
JRuby does with the JWM or IronRuby with CLR) is a more promising 
approach if you want to speed up Ruby execution.
