ccache , the compiler cache, is a fantastic way to speed up build times for C and C++ code that I previously recommended. Recently, I was playing around with trying to get it to speed up my Linux kernel builds, but wasn’t seeing any benefit. make -j4 2008.93s user 231.69s system 346% cpu 10:47.07 gcc version 5.4.0
