I would be very interested in seeing this too as your numbers look extremely good
As stated, the numbers are basically hogwash until all three forms are all tested on the same hardware using the same compiler. I *might* have time tonight to work on the code that the others posted above to get it compilable, although it is rather irritating that they posted code that was incomplete, but meh. If I have time tonight then I can test all three versions using MSVC8 on WinXP on my old 1.8ghz Opteron CPU.
Who knows, one of the other version may still be faster, MSVC does tend to handle optimizing heavy templated code better then other compilers, and Spirit is nothing but basically to be inlined templated code, so it might be able to optimize the xpressive version better as well, and who knows how it will handle the original code.
I thought Rob posted his code as an attachment here:

Is that not complete?
Have you tried compiling it? No, it is not complete, first of all it is missing the includes, as well as a main function to run the loops and test the timings in. :)
