The second build included TRYBROKEN so tried to build more ports and took slightly more time overall, but comparing the overall build duration (wall clock) of various ports is illustrative. llvm90 took the longest to build; it was 21:15:58 in the first run and 19:54:32 in the second. qt5-webkit went from 12:13:21 to 11:39:21. rust went from 15:14:46 to 13:49:50. firefox from 7:24:21 to 7:08:35.
