I don't think it's just about (or even mainly) functional programmers. Look on something like java or kotlin, that are inherently slowing down EVERY.SINGLE.VARRIABLE. access by boxing them into objects. On other hand there is rust, which takes quite a bit of inspiration from fp aproach but obviously still cares about the performance.

Java ints etc are not boxed, right?

  No, but as soon as you want to use anything like standard containers, you need to box them.

  "int" is not boxed but "Integer" is. You can't use primitive types like "int" inside generic type arguments so in that case you're forced into using the boxed integer type.
