Good point, here is the result from my machine:

(configured with ./tools/testing/kunit/kunit.py config --build_dir <dir> --make_options LLVM=1 --arch arm64 --kconfig_add CONFIG_RUST=y --kconfig_add CONFIG_SMP=y)

make ARCH=arm64 O=.kunit-next --jobs=40 LLVM=1 975.55s user 62.11s system 2159% cpu 48.054 total

make ARCH=arm64 O=.kunit-syn --jobs=40 LLVM=1 1022.36s user 62.38s system 2243% cpu 48.357 total
