How are you handling cache invalidation and mirror selection to hit that 2x boost? Curious if this works smoothly alongside standard Homebrew taps without breaking existing formulae.
There is no mirror selection, all bottles are downloaded directly from GHCR's CDN.
The speedup comes mostly from one shot resolution, intelligent download scheduling and parallelization of install and postinstall work.
Packages are installed to /opt/glustore so they don't affect Homebrew installed packages.
