Richard Grimes said:I did it with a Fast Fourier Transform, compiled as managed C++ and native
C++. I ran the managed C++ library once before running it through a timing
loop (this was to discount the effect of JIT compilation).
Somewhere I have the results, but they varied depending on the
optimization switches I used. The fastest time was for one of the managed
C++ builds, but only just.

Richard,
Note that the topic is C# vs. C++, if you run your FFT using C# you will
notice a performance drop compared to managed C++ (I guess you are refering
to C++/CLI) . This is the result of a slightly better optimization done by
the managed C++ compiler.
