The goal is to reduce layer sizes to optimize cold starts (that's the theory at least). - `strip` debug symbols for all libraries and PHP extensions (saves 11.7%) - compile PHP with the `-Os` C/CPP flag to optimize the binary for size (saves 8%) - compile libraries with the `-Os` flag (saves 6.3%) - disable the `soap` extension by default to avoid loading it on PHP startup (the only big unpopular extension I could find) - bundle the `pdo-mysql` extension in the PHP binary: it is extra small and will avoid loading it through an external file (small optimization) In total that's a 24% size reduction, i.e. 14.6MB. This is for Bref v3, I will run some benchmarks as just measuring the layer size doesn't tell us the full story about cold starts.

This could probably be backported to bref 2 without any issues. |

Yes but there is some uncertainty on whether |

Ah, good point. |

I'll run some benchmarks and see if there is any noticeable change |
