I'm also curious what the difference performance characteristics are (Spirit / Xpressive).
I'm not quite keen on apples-oranges comparisons. Both xpressive and Spirit have their place. That said, I am not aware of any formal benchmarks, but there's an informal one posted by Overmind on the Boost users list:

With that simple test, Spirit beats highly optimized xpressive (1.5 secs vs. 9 secs). You might want to read the whole thread.
What's disappointing is that after I did, finally, post real code, that thread fizzled.
It would be a nice addition to the documentation to have some thorough benchmark tests. Any particular ideas on what good tests would be? Maybe even just a note in the FAQs with a suggestion on how tests could be run, and asking for users to contribute, would yield some help from others. I would imagine that there have been a few users who ran their own internal tests before choosing a solution, if they were made aware of the interest in gathering those results, they may volunteer that data.
