Performance comparison between IronRuby and IronPython

We're aiming to implement a scripting mechanism, using DLR's Microsoft.Scripting and hosting as开发者_JAVA技巧sembly.

Now, someone knows about any performance difference between IronRuby 1.0 and IronPython 2.6?

To my understanding they have different compilers, but IronPython seems more mature and tested, but if anyone has documentation or knowledge on this issue, that would be appreciated.

IronPython has had more time to focus on performance improvements, but IronRuby has made significant performance improvements as of late. However, we rarely pin IronRuby up against IronPython. While people may comment here that one or the other is faster, and certain special cases/examples may even be uses to prove this, there is no exhaustive comparison available today.
