I'm fine with splitting things into something like "Basic Benchmark" and
"Expert Benchmark" ('view' sounds inappropriate), but as long as both
benchmark do the same thing, I don't see the problem why the expert
version cannot be a refinement of the basic version. Could you please
elaborate?

Looks great, this is a really useful graph (something is fishy with the
values on the y-axis, though...) :-) Can you please draw the x- and the
y-axis in logarithmic scale and make the vector increment a
multiplicative factor (2 by default)?

This looks quite okay, actually.

There should be a third size for Blas3 part. This will then also make
all four boxes (Blas3, Sparse, Copy, Vector) equally high, which should
improve the visual appearance.

Not yet, I'd say.

I don't see a problem with making the string conversion routines public,
so I just pushed a commit for doing so. :-)
Thanks and best regards,
