piuparts-report before:

805.65user 680.19system 3:14:41elapsed 12%CPU (0avgtext+0avgdata
1142932maxresident)k
459920inputs+19309536outputs (221major+15613680minor)pagefaults 0swaps

piuparts-report after:

771.61user 668.81system 3:11:11elapsed 12%CPU (0avgtext+0avgdata
1146840maxresident)k
470824inputs+19309296outputs (204major+15434860minor)pagefaults 0swaps

so no change in memory usage, the change in time is not significant (and
may depend on overall system load) or whatever

probably more interesting would be benchmarking runtime of master as
that will only need to partially compute rdeps
