In this talk, Łukasz will present his workflow for:
- identifying the most significant optimizations,
- ensuring that you optimize what your organization actually cares about,
- ensuring that your optimizations translate to real gains in production, and
- quantifying the impact and presenting gains
which he used to save significant CPU at Google.
We'll also go through a workflow for understanding Go CPU and memory profiles as well as a few examples of real performance issues and optimizations.
