Before, it had been 20 seconds. I've just done the whole top level for gnome-control-center and it went down from ~49 seconds to ~6. There is a big jump very early when doing that. I can only speculate, but I think we would hit some limit in make after which it went into some degenerated and very slow state. Either because it keeps a list of all file ever included somewhere, or because of the ever-growing BUILDLINK_ORDER variable. Speaking of BUILDLINK_ORDER, I'd like to tweak slightly my proposal for how bl3.mk files should look like, and move BUILDLINK_ORDER management in the space executed at every inclusion. It does make it grow larger, but it will make show-buildlnk3 output more useful than if it only shows the location of the first inclusion. An alternative is to manage it both in the "first inclusion" part and the "top-level inclusion" part, but it's a bit more complicated. -- Quentin Garnier - cube%cubidou.net@localhost - cube%NetBSD.org@localhost "See the look on my face from staying too long in one place [...] every time the morning breaks I know I'm closer to falling" KT Tunstall, Saving My Face, Drastic Fantastic, 2007.
