[jruby-dev] short methods names faster?

[Micah Martin]

In a recent competition I held using JRuby (http://blog.8thlight.com/articles/2009/10/4/reflection-on-hangman 
), one of the competitors made a very interesting observation about  
the length of JRuby method names...

"Actually I choose short method names because it was significantly  
faster in jruby. I think the speed increase was something like 10-20%  
on one letter method names."

I found this a bit shocking.  How could that be true?
