Ask HN: As a developer, how is your performance measured
Is it measured by how much code you ship,
how many on-call problem you saved,
or how much OT you willing to take?
To messure it well you need someone with good taste (which is had to find developers often dislike other peoples code for no good reason).
From your 3 options its only on code you ship thats cared about. But its quality and volume.
