I use ccache with

cat /var/cache/ccache/ccache.conf

max_size = 20G
umask = 002
compiler_check = %compiler% -v
cache_dir_levels = 3
compression = true
compression_level = 19

ccache uses zstd for compression. The higher compression level may slow down the compilation process. A compression_level of 1-3 can be a wise decision for faster compilation. ccache supports the recompression of the cache with --recompress <LEVEL>. see ccache -h, ccache and facebook.github.io/zstd/
