charset="utf-8" From: Thomas Huth Uploading the cache from the runner takes a long time in the MSYS2 job, mostly due to the size of the compiler cache. However, looking at runs with a non-poluted cache, it seems like you can get a build with a 99% hit rate already with ~ 160 MiB cache size, so the compiler cache with 500 MiB certainly contains a lot of stale files. Thus decrease the size of the ccache to a more reasonable value to speed up the MSYS2 job in our CI. While at it, also add a "du -sh" for the build folder to get a better feeling for the amount of object code that is required for the build, and publish the list of files in /var/cache to be able to better analyze what is really clogging our cache here.
