got benchmarks?

benchmarks? comparisons to other c++ libs?

None and none. I never actually compared it to other C++ interpolation libraries in regards to speed or memory. My focus was on delivering a great API and in that regard I believe tweeny to be one of the best if not the best (of course I'm biased ;)

I suspect it is not going to be particularly fast, it has no processor optimization nor any kind of optimizations like those you typically see in math libraries.

But I suspect it is not going to be particularly slow also.

Sadly I don't have any hard evidence to support my suspicions so if this is a topic that really concerns you, you shouldn't believe me and try to benchmark it yourself.
