Any updated (modern) browser should be able to see webp just fine, I'd rather just serve it without a backup plan if I'm planning to have webp in my website.

But to know via scientific method requires proof (or disproof) by experimentation

Fair enough. But it is needed to point out that there's a catch in that in order to use dynamic dispatch (subclasses, interfaces, ...) you'd still need to use pointers in C++.

Deep down the problem could be rephrased as "there are no structs in Java". In C# for example you could have a vector of structs and enjoy linear memory access.

If you aren't using OOP features (such as inheritance), you're not really doing OOP, despite using C++.

In the case of C++ I'd put something like: you can use free or costly abstractions, and OOP in general has a preference towards costly ones.

Also vector is a weird point to make, it's been some time I had to deal with Java (luckily) but arrays there are also linear AFAIK. And there are GCs that have a bump allocator for new objects (not sure if Java fits here), so cache would benefit more than in sparse malloc allocations in C/C++.

(As with OO) depends heavily on implementation, but my 2 cents is that functional doesn't apply as much constraints to optimization.

If a compiler is sophisticated enough a functional program should perform as well as a procedural one that uses a comparable garbage collector. But of course real compilers have shortcomings.

I recommend taking a read at Haskell's wiki performance article[1] to have an understanding of the shortcomings that are specific to Haskell.
