*The problem is*: Given a number of programming libraries with similar or equal scope (e.g. XML parser, regex, markup, ...); are there tools, with which one can run performance tests on these libraries and compare (and generate reports), even though the libraries may be written in different programming languages (such as java, C#, ruby, python, perl, ...)?

I looked at these [opensourcetesting.org/performance.php](http://www.opensourcetesting.org/performance.php), but none of them fitted into the (somewhat blurry) requirement above.

Are there toolkits or frameworks out there for cross-language cross-platform performance tests?

Thanks.
