Well, it takes about 1 minute and 15 seconds for x11/xorg on my system, which has 273 dependencies, with my optimizations it still takes 60 seconds. Parsing bsd.port.mk takes an average of 0.2 seconds on my system. 0.2 * 273 = 54.6 seconds. Which looks like the major part of computation time to me. The only way to avoid this I see, is to abandon the recursive pulling in. Packages wouldn't know all their dependencies any more, but the dependencies would still know what they depend on and so forth. I will just change my system and see weather it breaks. I suspect that some things like pkg_add -r would have to be slightly adjusted to support such a change. _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "[EMAIL PROTECTED]"
