Well, bragging about speed is silly, it makes the other side improve their
act and challenge you.  It´s better to enjoy the performance gains but not
brag too much about it. :-P

I find language wars silly, really, specially when benchmarks are involved.
The biggest advantage for jruby is its access to a wealth of java
libraries, not speed. (well, if it´s got good speech, much better, but it´s
a side benefit).
