		fny on July 22, 2015 \| parent \| context \| favorite \| on: JRuby 9000 released The real advantage comes from the fact that JRuby isn't enslaved to a GIL like MRI, so you get JVM threads out of the box. Even with the JIT, JRuby (at least 1.7) isn't appreciably faster than MRI when running a single-threaded app: http://www.isrubyfastyet.com/

These benchmarks are very small and do not run long enough for the JIT to really kick in. Many of them are also so synthetic as to be meaningless.

50,000 requests aren't enough for the JIT to warm up?
