# We only have 5 GiB of cache available *in total*. Beyond that, GitHub deletes caches.
# Currently, we use about 130 MB for the two toolchains (i686 & x86_64), and three ccache caches:
# One with ALL_DEBUG (i686) and two with NORMAL_DEBUG (i686 & x86_64).
# Therefore, using 1.6 GB or more per cache causes disaster.
# Building from scratch fills the ccache cache from 0 to about 0.7 GB, and after compression it comes out to
# about 0.25 GB, so 3 GB (1GB after compression) should be plenty, all while comfortably fitting in the cache.
