Not enough to add 40% overhead to a 1mb file read, I can tell you that much.

It depends. If disks got so fast that function call overhead starts to dominate, then you might see an effect like this. But I have to imagine reading from an SSD is still 1000x slower (at least) than a function invocation in Javascript.

I don't see that basically ever being the case.
