Reduce Chromium re-compilation time

Question

Every time I execute git rebase-update & gclient sync -D, it will take me 4-5 hours to recompile. Is there any method to reduce the time needed?

Answer 1

• Use compiler cache: https://ccache.dev/

• I'm not familiar with Chromium, so if there's any option to exclude building code for architectures other than your computer's, use that.

• Don't build tests etc if you don't run them.

• https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/mac_build_instructions.md#Faster-builds

• Ask on Chromium forum/ discussion groups https://www.chromium.org/developers/discussion-groups
