I wasn't about to mention this, but since you reposted it I will. I
shared the original post with a number of people and at least three
mentioned it.

The term "low performance overhead" just seems to make people thinks
it's slow, and they don't read past it. I highly suggest either "low
overhead" or "low performance impact" would avoid this.

Perhaps I just know a lot of other people who suffer from literalism.
