Of course, it's always better with actual benchmarks. In normal cases, the dependency checking will be often twice as fast.
Ways worse in some pathological cases: make package in lang/php/5.2 before: 3m06s after: 1m06s -> /3 make print-package-signature from the top-level: before: 230m21s after: 30m52s -> /7 !! make package in meta/gnome before: 11m43s after: 32s -> /20 !! typical out-of-date run (300 packages) before: 4m53s after: 1m40s -> /3
