I did some more measurements in the same environment, but this time I was building with `-j12` and using your cmake command line. My environment: - Gentoo amd64 - system-wide -O3 and LTO, including GCC - AMD Ryzen Threadripper 3970X @ 3.7GHz, 32 cores/64 threads One modification I made was `ccache -C` between the cmake call and the first unmeasured cache warmup build. The new results: ``` compile-time branch: warm ccache: 1:53 1:36 1:37 (median -11%) cold ccache: 4:26 4:34 4:30 (median -7%) main branch: warm ccache: 1:49 1:51 1:48 cold ccache: 4:51 4:52 4:49 ``` There is some variability in the results, and I think your numbers are affected by that. I can do some more measurements on a laptop later. -- This is an automated message from the Apache Git Service.
