There should be no surprise that interpreted, dynamic languages are utterly out-gunned as compared to compiled (JIT'd or otherwise) languages. It's inherent to the system - every little thing you do costs more.
Many people choose Ruby and figure, given that premature optimization is the root of all evil, they'll optimize later if needed.
That's like choosing between a farm tractor or a ferrari - and figuring if the tractor doesn't perform up to snuff, we'll add a spoiler (and given the 10x disparity between Java and Ruby in some of those graphs, if we throw out a 20mph top speed for a farm tractor, the ferrari analogy is actually rather spot on).
There are many good reasons to choose dynamic/interpreted languages - but always know you're giving up performance in exchange.
