Summary

Diverse experiences Motivated by software quality Interest in improving tool support Curious about ESO team

The end

Thanks for listening

Why this project?

  • Google open-sourced Bazel
  • "After switching from x to Y, our builds got 50% faster"
  • What features exist? What are the downsides?
  • How to convert?
  • Maturity of alternatives?
  • Get objective facts. Repeatable. Open.

Why does performance matter?

  • Short iteration cycles
  • Higher tool acceptance
  • Better code quality

... but only one of many evaluation facets.

Framework setup
