How do you compare valarrays performance against inline arrays?

Question

Is there a significant penalty for using the more convenient valarray over inline arrays? Do you know about some tests?

Answer 1

valarrayaims to improve the chances of getting good optimization. For better or worse, it has become something of a forgotten step-child of the standard library; I don’t know of any implementations that do a lot to take advantage of what it provides. Worse, the design was really designed for vector processors and doesn't work very well with processors that use caching heavily - which is almost all the more.

However, I'm curious why you want to do this instead of using vector?
