Description
Mold is a new linker that says it is faster than lld and gold. See https://github.com/rui314/mold
Hand testing it on my machine, it makes a big difference in speed of iteration:
# Test case: # - Start with fully built impalad # - touch be/src/scheduling/scheduler.cc # - time make -j12 impalad With Gold (current default): real 0m15.843s user 0m15.478s sys 0m2.127s real 0m15.820s user 0m15.302s sys 0m2.157s real 0m16.136s user 0m15.799s sys 0m2.098s With Mold: real 0m2.479s user 0m2.169s sys 0m0.958s real 0m2.674s user 0m2.218s sys 0m1.086s real 0m2.524s user 0m2.136s sys 0m1.042s
This seems like something we should investigate further.
